They did fuck before, yeah. Inoch liked him and was upset that Taegung likes mc. But they stop doing that since Taegubg likes mc and mc and Taegubg start having sex and dating sort of(?) I’m ngl I don’t remember much, I read this awhile ago and forgot most of it. I just know Inoch likes Taegung and dislikes Shinwoo bc he’s jealous that Taegung likes Shinwoo, Inoch and Taegung did sleep together as sex friends, Shinwoo slept with Inoch and Taegung…Inoch fucking sucks and Taegung claims to like Shinwoo but did absolute shit when it actually came to advocating and protecting him
And SPOILER
years in the future, Taegung and Shinwoo have separated for like 10yrs or something idk. Inoch tried to have Shinwoo get gang raped in the past essentially, causing a “fall out” between Inich and Taegung. But Shinwoo broke up with Taegung and moved away. Years later he works with a show director(?) and meets Taegung again. Despite what Inoch did and even Taegung’s past with him, Taegung id STILL in contact with Inoch and even helps him with work and is still sort of his friend. Makes absolutely no sense and just shows how shitty both he and Inoch are -_-

First off, I hate this whole dynamic with all three of them. It’s so weird, rushed, messy, and flippant. Second, Taegung is still an asshole. Whether he bullied Shinwoo, asked his friends too, or did nothing about it he’s an asshole in all scenarios. He still associated with jerks who harassed and beat Shinwoo and never told them off. AND he himself was also rude to Shinwoo many times. Then, he still sat by and watched his friends harass Shinwoo yet again. Sure, he stepped in at some point but he damn well took his time. The moment thwy dragged him in that room or started being weird he should’ve stopped it. Yet Shinwoo is apologizing? And going “oh I misjudged you”. Utter bullshit. Taegung fucking sucks and Inoch seems shitty too (haven’t gotten far enough to judge yet)
Edit: and this bitch is cheating on his girlfriend with Inoch and Shinwoo? The audacity.
Inoch also does suck ugh
