Not even.. Ohn literally fell for Seowoo without him even trying. He didn't even need Jaewoo because Ohn likes that Seowoo is shy. So no Seowoo didn't just "snatch" Ohn told them both to win him over and Seowoo did because he's Ohn's type
But the one Ohn fall for in the first place is Jaewoo he's just playing a part as Seowoo if it wasn't for Jaewoo, Ohn would not look at Seowoo shy side as 'cute' the first time Ohn see Seowoo at the sidewalk he's not impressed at all, but when Jaewoo started following him that's where things started to change he likes how shy Seowoo is because from his perspective Jaewoo can be acting cool and also shy and crybaby at the same time that's what Ohn fall for
So in conclusion ITS ALWAYS BEEN JAEWOO but when they both tried to pursue Ohn together he just chose Seowoo over Jaewoo (so basically Seowoo snatched Ohn from Jaewoo)
No he THOUGHT he fell for Jaewoo but that wasn't the case. He fell for Seowoo's shyness. The pool chapter, movie chapter. Mainly the pool chapter, that is where Ohn started to catch feelings and that was the real Seowoo
Na. I like Jaewoo but Ohn had been dreaming about Saewoo even before he knew they were two. Jaewoo gave him the strength to be himself, just like Ohn gave Saewoo the strength, but the one who stole.his heart was Saewoo. Saewoo was not only his fan, he and Saewoo first binded over their shared bully trauma and that's why he started warming up to Jaewoo. Jaewoo broke the barrier that Saewoo weakened.
It's not fucking fair for Jaewoo!!!!! He looked so hurt when they are at the school talking. It's so obvious that Ohn told he wanted to be remain as friends with him???? Like why tho?????? I know Seowoo has social anxiety and asked his brother for help but what did he expect??? There is a possibility that Ohn and Jaewoo would end up liking each other. But then when Ohn started showing signs he just snatched up Ohn from Jaewoo like hell I would root for that shit! ALWAYS TEAM JAEWOO
(p.s. the personality of Seowoo after seven years is no different from Jaewoo personality from seven year before like duh???)
