They are both wrong. None of them have communicated what they feel. There's nothing wrong with having boundaries, and feeling how they feel, but what is wrong is that they're not telling each other those feelings, so neither of them know what the other is thinking because they won't tell. They're both not mind readers, and know exactly what the other thinks it's not rational. Both need to work.The only thing that made this little bit I guess worse, on his part is that he did hit him, but then again he already told him no, and tested his boundaries a little too far, and found out so I can't even actually say he was wrong for that either. Both did wrong, but they can overcome it they just be honest with each other.

I agree with you 100%! But unfortunately it's a story... what's a love story without miscommunication haha....haha....but nevertheless, it is important to consider their backstory too to slightly justify their thought process, for now idk if uke even has a valid backstory but we'll wait and see.
But if put irl terms, you're absolutely right that both parties would be at fault :)
It really goes to show who will be a green flag and red flag in a relationship. Siding with uke is a big RED flag. He literally brings up his experiences of being with others in bed DURING SEX then proceeds to get jealous through just surface touches of peers, not even an arm wrapped around, JUST FINGERS TOUCHING. Then he goes to give seme the rude responses and silent treatment??? Where's the communication? Why leave seme in the dark and treat him like shit then get mad? Seme is in the right here, he surpressed his emotions so that his feelings doesn't burden uke, especially when he knows uke was someone who slept around. Insecurities tend to rise up when one hasn't been in a relationship b4, especially with a character like uke's, it's damn risky, feelings get wavered easily. He's scared that uke will leave him, that's why he doesn't say much. It's a very valid response considering his backstory/trauma (as someone who got bullied back when I was a kid for liking "weird" stuff, I get him).
For people agreeing it's a valid crash out, please don't treat your partner/future partner like that... You'll be the problem. (Possibly 50% chance give or take ur partner ain't an ass)
