Stobin

Stobin is the friend ship between Steve Harrington and Robin Buckley from the Stranger Things fandom.

Canon
Steve and Robin begin as coworkers at Scoops Ahoy. Steve spends most of his time trying to flirt with female customers, Robin keeping track of how many times he's failed. When Dustin shows up to speak with Steve, Robin jokingly says "your friend's here."

When Robin discovers the conspiracy Steve and Dustin have gotten involved in, she offers to help them, no strings attached. While she translates one of the messages, Dustin and Steve discuss the latter asking her out.

While investigating a transportation company, the three of them hide on a roof. Robin and Steve hold hands without noticing, pulling away when they realize it.

Later in Season 3, Robin and Steve get captured by Russian agents. Steve is drugged, causing Robin to panic and spit in the guard's face. They attempt to escape once the guards leave and fall over, laughing hysterically at their predicament. Steve admits he regrets not talking to her in class and says "it was fun while it lasted."

Before getting broken out, Steve and Robin are injected with a truth drug. They suffer the euphoric side effects for most of the episode and get put in a movie theatre by Dustin. There, the two friends eat popcorn and laugh about their confusion. Eventually, they leave the theatre to get water, before throwing up in the bathroom.

While in the bathroom, Steve tells Robin about his history with Nancy and that he now has feelings for someone else. While she is very flattered, she comes out to him as a lesbian. Steve takes it very well considering the time period and says he's okay remaining friends.

In the final episode of Season 3, Steve and Robin apply for a job at a video store together. Robin helps Steve get through the interview after he bombs it, and they both get hired.

Fanon
When Robin was initially introduced, the fanbase started shipping her and Steve. Now that she has come out as a lesbian, many people have turned to shipping them platonically. People also greatly appreciated Steve's reaction to Robin coming out, another sign of his character development.

On AO3, Robin & Steve is Robin's second most written ship and Steve's tenth most written. The Robin/Steve ship is noticeably less popular.

Trivia

 * Robin and Steve were actually supposed to get together originally. The actors and producers decided it would be more natural and a better story if Robin turned out to be lesbian.
