I don't like where this story is heading either, but blaming Yuta for not trusting Seunghyun enough feels unfair.
It's been ten fucking years. Seunghyun left him behind for an entire decade, and now they've only been back in each other's lives for about a month. Why would Yuta suddenly believe that Seunghyun would choose him over the people he's spent his whole life protecting—Jaeil and his sisters?
Deep down, Yuta already knows who Seunghyun would choose if it ever came down to it, and it wouldn't be him. So why wait for that moment to arrive? Why not end everything now while he can still protect Seunghyun and spare himself the pain of being abandoned and not chosen all over again, just like he was ten years ago?

Like what’s up with Yuta? I’m in no way victim blaming or anything, I know Seunghyun never should have left him but now that he is trying, why can’t Yuta accept? Why did he follow them? I’m just genuinely curious. Where is this manhwa headed
