I think it was more bc he was always rough w him during sex and sooyoung just put it w it I don’t think he liked it or disliked it... and then when he hit him that was the final straw bc he’s used to getting hit during boxing but not from someone he trusted- also he did insinuate that sooyoung spread his legs before he acc did so that deserved a slap tbh lmao he was being rude as hell

The MC and hyung's relationship starts to go downhill when the hyungs father (gyms manager) discovered their relationship, I think thats when MC starts pushing the hyung because of that.
I think the "abuse" is when the hyung hits back the MC when the MC gets pissedp because the hyung telling him "that he spread his legs for the boss" and hits him. More than of physical abuse, it is an emotional one since during that time the hyung is the only one that made the MC live through life and made him feel the he matters.
I don't think the MC hates their rough sex, or at the least it was not discussed if he hate it or not only that they usually had rough sex.
idk if I just didn’t pick up on the context clues but I didn’t completely comprehend how the ex abused the uke... lowkey I thought it was just a toxic relationship because the uke would also hit the seme and In the story I’ve only seen the same hit him once while the uke slapped him around a bunch
