Byler

"Do you remember the first day that we met? It was... It was the first day of kindergarten. I knew nobody. I had no friends and... I just felt so alone and so scared, but... I saw you on the swings and you were alone, too. You were just swinging by yourself. And I just walked up to you and... I asked. I asked if you wanted to be my friend. And you said yes. You said yes. It was the best thing I've ever done."

- Mike to Will, The Mind Flayer

Byler is the slash ship between Mike Wheeler and Will Byers from the Stranger Things fandom.

Canon
Mike and Will met on the first day of kindergarten in 1976. Mike approached Will while he was alone on the swing set and asked him to be his friend, to which Will agreed. Mike later tearfully described this as the best thing he had ever done.

Season 1
"I'm the only one that cares about Will!"

- Mike

In 1983, Mike and Will are playing Dungeons & Dragons (D&D) with their friends, Dustin and Lucas, in Mike's basement. Mike, acting as Dungeon Master, summons a Demogorgon which ultimately defeats Will's character when Will rolls a low number. Mike is, however, not aware of this as he didn't see the result of the dice roll. Although Lucas tells Will that his roll doesn't have to count since Mike didn't see it, Will still lets Mike know that he rolled too low before leaving for home.

When Will goes missing, Mike begs his mother to let him search for Will, which she refuses, leading Mike to angrily claim that he is the only one in his family who cares about Will. Mike then convinces Lucas to go look for Will by reminding him how, when they were playing D&D, Will chose to help the party (the name they call their group) instead of playing it safe, thus putting his character in danger.

After Will is presumed dead, Mike returns home in tears and is comforted by his mother. He later sits in his basement, dejectedly looking at a collection of Will's illustrations. However, when Eleven proves that Will is still alive, Mike is determined to find him. During Will's memorial assembly, Mike notices Troy and James mocking Will and publicly confronts them. When Troy makes insulting comments about Will's sexuality, Mike shoves him to the ground and Eleven uses her powers to humiliate him.

After Will is found in the Upside Down and hospitalized, Mike sits awake at the hospital as he waits for him to wake up. When Mike, Dustin and Lucas reunite with Will, they embrace him and share the chain of events that occurred while Will was gone.

Season 2
"Hey, well, if we're both going crazy, then we'll go crazy together, right?"

- Mike

In 1984, Will joins Mike, Dustin and Lucas at the Palace Arcade to play games. Will experiences an episode, finding himself in a seemingly abandoned version of the arcade in the Upside Down. He steps outside to see a storm raging in the sky before Mike snaps him out of it and leads him back inside.

On Halloween night, Max, a new classmate of the boys, joins them in trick-or-treating, which causes Mike to become upset as he did not agree to Max joining their group. He expresses his annoyance to Will before walking ahead. As Will follows him, he begins experiencing another episode, again finding himself in the Upside Down, and calls for Mike before seeing a shadow-like creature in the sky. He is snapped out of it by a concerned Mike who takes him back to his house, telling the others to continue without them. In Mike's basement, Will describes his episode to Mike and begs him not tell the others as he believes that they wouldn't understand. Mike claims that Eleven would understand and admits that he sometimes senses her presence, and wonders if he is going crazy. When Will says that he feels like he is going crazy too, they promise each other that if they both go crazy, then they will go crazy together.

After Will gets possessed by the Mind Flayer, Mike goes to his house to check on him and Will explains his connection to the Mind Flayer. Mike says that it may be a good thing as Will can now spy on the monster which may lead to them figuring out how to stop him. When Will expresses fear over the monster spying back, Mike assures him that they won't let him. Mike then sleeps over at Will's house. When Will is later taken to Hawkins Lab for inspection, Mike is the only friend to stay by his side. Will suffers memory loss when he awakens and is only able to remember Mike and his mother, Joyce, out of those present.

While attempting to bring Will's memories back and to learn the Mind Flayer's weakness, Mike tearfully tells him about their first meeting on the first day of kindergarten and how asking Will to be his friend is the best thing he has ever done. Joyce and Will's older brother, Jonathan, also share stories involving Will that are personal to them, which enables Will to signal them in Morse code how to stop the Mind Flayer.

A month after Eleven forces the Mind Flayer back into the Upside Down and closes the gate between the two worlds, Mike, Will and the others attend the Hawkins Middle School Snow Ball. When a girl asks Will if he'd like to dance, he is hesitant, but Mike's urging causes him to say yes.

Season​ 3
"It's not my fault you don't like girls."

- Mike

In 1985, Mike, Will, Lucas and Max sneak into the movie theatre at the Starcourt Mall with the help of their older friend, Steve, to watch Day of the Dead for free. After a sudden power outage, Will feels a strange sensation at the back of his neck. Mike senses that something is wrong and asks Will if he is alright, to which he replies that he is fine.

Will is later upset with how much time Mike is spending with Eleven, preferring more time for D&D campaigns. After Eleven breaks up with Mike, Will tries to play D&D with Mike and Lucas but their disinterest in the game upsets him. When they attempt to apologize, Will brushes them off and storms out of the house. Mike catches up to him and in a heated argument, he says that it's not his fault that Will doesn't like girls which leaves Will speechless. He adds that they've grown up and they can't spend the rest of their lives playing games in his basement. However, Mike regrets his words as he watches Will leave in tears. When Mike and Lucas go to his house to apologize, Will, having realized what the sensation in his neck means, tells them that the Mind Flayer has returned.

Three months after defeating the Mind Flayer, Will and his family, along with Eleven, are moving out of Hawkins. When Will puts his D&D items in the donation box, Mike suggests that Will should keep them in case he ever wants to join another party but Will assures him that he will never do so, causing them to smile at each other. Mike and Will are later emotional as the Byers and the party tearfully say goodbye.

Season 4
"It's just... It's Hawkins. It's not the same without you."

- Mike

In 1986, Mike reads a letter from Eleven, where she says that Will has been working on a painting which he refuses to show anyone and Eleven assumes it's for a girl. When Mike visits them in California, Will and Eleven are both eager to see him. However, while Mike joyfully reunites with Eleven, his reunion with Will is short and awkward. Will had brought the rolled-up painting with him but when Mike asks him about it, Will simply says that it's a painting he's been working on.

Will, Mike and Eleven later go to Rink-O-Mania where Eleven lies to Mike about her social life. Will grows annoyed at her lies and privately confronts her, saying that Mike doesn't deserve being lied to but Eleven, although affected by his words, ignores him. Mike and Eleven then skate together while a dejected Will skates behind them. When Will tells Mike that Eleven hasn't been telling him the truth, Mike doesn't believe him until he sees her being humiliated by the people she claimed to be her friends. She runs off and as they look for her, an annoyed Mike accuses Will of being unkind to her only for Will to point out that he's been forced to third-wheel all day and how miserable he has been. Mike brushes him off and Will asks Mike why he barely called him and only wrote letters to Eleven. Mike replies that Eleven is his girlfriend while Will is his friend, and Will retorts that they used to be best friends. Mike then points out that Will is equally to blame for not reaching out more.

When Eleven is taken away by Dr. Owens, Will listens as Mike admits that he fought with Eleven before she left and regrets not having told her what she wanted to hear. Will comforts him, saying that Mike can tell Eleven whatever he wants to say when they find her. Mike later thanks Will for comforting him and apologizes for the way he behaved towards him. Will attempts to say that he deserved it for not being more considerate towards Eleven but Mike immediately disagrees, saying that Will didn't deserve being treated that way. Mike then reveals, much to Will's surprise, that Hawkins has not been the same without him and that they would work better as a team or best friends, to which Will happily agrees.

On their way to find Eleven, Mike grows worried over her not needing him anymore and shares his concerns with Will. Attempting to comfort him, Will shows Mike the painting he has been working on, lying that Eleven asked him to make it. Mike is amazed by the painting which turns out to be Mike, Will, Dustin and Lucas -- dressed as their D&D characters -- fighting off a three-headed dragon. Will points out that Mike's character is the heart of the group and that they would fall apart without him. Will then emotionally expresses his romantic feelings for Mike, disguised as Eleven's, and says how Mike makes "Eleven" feel better for being different and that "she" will always need him. Will's words reassure Mike about his situation with Eleven but he remains oblivious to Will's feelings and doesn't notice when Will turns away and cries silently.

When Eleven is trapped by Vecna, Will reminds Mike that he is the heart of the group, encouraging him to confess his love for Eleven, which gives her the strength to break free of Vecna's grasp. Although they were able to wound Vecna, Will senses his presence when they get back to Hawkins and tells Mike that Vecna won't stop until he's killed everyone. Mike comforts him and assures him that they will stop Vecna once and for all.

Behind the Scenes
"S4 has me shipping byler over anything... vol. 2 now!!"

- Noah Schnapp

"Normalize kids with bad haircuts making veiled love confessions in the back of pizza vans"

- Randy Havens referring to Will's monologue to Mike

"Will unzips his backpack and hands him his (now slightly crumpled) ROLLED UP PAINTING. Mike removes the twine that clasps it, then unfurls it. His breath catches. IT'S AN INCREDIBLY DETAILED, STYLIZED IMAGE OF MIKE, WILL, AND THE OTHERS -- DRESSED AS THEIR D AND D CHARACTERS -- FIGHTING OFF A THREE-HEADED DRAGON. MIKE IS LEADING THE CHARGE, THRUSTING HIS SWORD BRAVELY AT THE DRAGON."

- Papa (official script)

"Will is watching Mike and El flirt through the porthole-style window of the pizza kitchen. Unable to watch them anymore, he returns his eyes to the dissolving salt. Jonathan eyes Will. He knows his brother too well. Knows he's hurting."

- The Piggyback (official script)

Fanon
Although Mike and Will had little interaction in the first season since Will went missing for most of the season, the pairing was still fairly popular, mostly due to Mike's determination to find Will. After the second season was released, they gained a larger following due to their shared interactions that often involved heartfelt conversations. By the third season, they had grown in popularity but were still overshadowed by Mike's canon pairing, Mileven. However, interest in the pairing grew considerably following the fourth season where it was revealed that Will is in love with Mike.

Most fanfiction revolve around Mike expressing his feelings for Will after realizing Eleven wasn't for him. Newer fics delve into Will's heartbreak over Mike dating Eleven, and Mike finding out how Will feels about him. On AO3, Byler is the most written ship for both Mike and Will. It is also the third most written ship under the Stranger Things (TV 2016) tag.
