im pretty sure they get together RIGHT after he breaks up w the brown haired guy.. either ...

Man I'd be so bummed out if they took the cheating route :(
Sunbae don't deserve that - mans been so patient too

They dont cheat, the bot breaks up woth him

I mean Iksu was gonna break up with him before but Sunbae stopped him and asked him to decide by showing up either on Dohun match or the concert ticket he bought. Iksu showed up on Dohun match.
Sunbae was really keen on suffering for someone who right from the start didn't like him back D:

I mean Sunbae forced Iksu to go with him, he never liked him n the Sunbae knew that?

he never forced him

he might’ve not psychically forced him but he did push him to it, the first time he tried to kiss Iksu he didn’t want to, the next time when Iksu went to his house he was being pushy with why would u follow me blah blah blah, n the kiss Iksu wasn’t into it n sunbae did push him into a relationship when he knew Iksu didn’t like him, there’s a very thin line between push n force

Tbf iksu never made it clear he didn't like it either like he could have been more transparent since sunbae was thinking iksu needed more time to adjust but like,,, the red flags continue,,,

I mean, it was very obviously he didn't like him ... they both were wrong, Iksu for just going with the flow and accepting going out with someone he didn't even like and the Sunbae for cornering Iksu into a relationship even though he knew he wasn't reciprocated and when he realized Iksu had feelings for someone else too ... in the end the Sunbae was just setting a heartbreak for himself ...
