Aquamelt is the slash ship between Aquamarine Hoshino and Melt Narushima from the Oshi No Ko fandom.

Canon
Aqua and Melt's first time meeting each other was on a manga adaptation drama production called "Sweet today". That said, Aqua started acting again after Kana Arima asked him to substitute an actor whose casted to play the stalker for "Sweet Today" as he kept on complaining about the filming set, to which leads the role getting unfilled. Aqua agreed on fulfilling that role for the play. When Kana and Aqua arrived at the filming set, they met Melt Narushima. He was calling Kana out to which Kana finds the opportunity to introduce Aqua to Melt. Aqua bowed his head, in order to greet him nicely. However, unfortunately, Melt passed him as he walks away with an arrogant way of saying 'hello'. Aqua was curious, asking about what is up with his attitude, leaving him no chance of asking the other's name.

As the last episode started filming, Aqua finds out that Melt's acting is quite terrible. So to enhance his performance, Aqua came up with the idea of provoking him, as he walked closer, whispering out "You're pretty ugly up close" on Melt's ear, to which Melt widened his eyes. He grabbed Aqua by the collar, shouting over him in rage, while little did he knew it was Aqua's plan all along. Aqua smiled, looking at how he accomplished on dragging Melt to play along.

For the last scene of the episode, Aqua jumped over the heroine in order to act as if he was about to kill her. That's when Melt punched him and it was enough to leave a bruise on his face. After the shooting ends, Aqua was rubbing the bruised part of his face with a towel. Looking at how Melt injured Aqua, he voiced his apology. Aqua said it's alright, he just wanted Melt to get fired up, saying that after all, acting should carry emotions along with it, as he complimented Melt saying that he have a good performance.

Aqua and Melt once again met each other during a production of a 2.5D stage play "Tokyo Blade". They met again during the first day of the cast meeting, in which Melt finds himself approaching Aqua and Kana on the hallway. Aqua gave him a blank expression after finding out that they will be casted to play together again. During the rehearsals, Yoriko Kichijouji oftentimes gave Melt a cold shoulder, such as greeting him with a stiff replies. Seeing that, Melt oftentimes came over to Aqua, complaining at how Yoriko kept on giving him a cold shoulder. To which, Aqua always seemed to respond with things such as saying that “you’re the guy who ruined sweet today after all” and “i guess she’s surprised that you have the guts to show up”. When some of the cast shows up at Yoriko’s house, it appears that Aqua and Melt is on the same age, since both of them mentioned themselves to be at the age of 16. And so, after the author of “Tokyo blade” speaks up, saying that her trait is to rewrite the entire script so it would include a much better spotlight for emotional acting, both Aqua and Melt wasn’t really sure about whether they could possibly act with emotions. It seems that they have one similarity : struggled on emotional acting. Melt fell desperate, saying that he won’t be able to do it with just a one month time span of rehearsals left. He said, it’s probably nothing for Aqua, but Aqua hesitates saying he wasn’t sure either.

Just when the day finally arrived, and the stage raised its curtains, Melt appears to be up on the stage first for the battle between Kizami and Monme. Even so, Melt’s acting remained terrible that moment. During his act, a flashback of him and Aqua appears, in which Melt asked Aqua for advices during their jogging time. Instead of giving him an actual advice, Aqua said that it’s not bad for Melt to be seen as crap. Melt questioned what kind of advice was it, asking him for something way more constructive. Aqua said that he never meant to put him down, instead he simply suggested him to utilize his shittiness better. So during the time where Melt was about to show off his sword trick, Aqua’s advices and words spoke inside his head as he continued acting. Till he succeeded on doing his sword trick, Aqua smiled behind the stage’s curtains. Right when the crowd cheered for Melt, Kana asked Aqua behind the stage, saying whether if it’s Aqua the one who gave Melt the idea. He simply said “not really”, in fact Aqua thinks that Melt is a hardworking person, and that he nailed it merely thanks to his own hardwork.

After Melt’s staging time came to its end, he went backstage as he remembered the thing Aqua had ever mentioned that acting should carry emotion along with it. He turned to Aqua, saying that he finally understood what he meant and admitted that it’s fun. Looking at how Melt took his advice to heart, Aqua smiled at it.

Trivia
On episode 3 of Oshi no Ko’s anime, or precisely on chapter 14 page 18 of Oshi no Ko’s manga, Kana appeared to misinterpret Aqua, saying that he “swung that way” when Aqua gets all interested on joining sweet today after she mentioned something about Melt.
