Saw a really introspective comment left on the Korean version of this episode that I wanted to share it here:
Emotional abuse is definitely worse than physical abuse because not only the characters but even the commenters, who are fully aware of Jahyeok's situation, do not see him as needing help; they view it simply as a personal problem. They are both in the same situation of being abused and unable to carry on with daily life due to their parents, yet it feels like no one sees this as the result of abuse. While personal circumstances cannot be an excuse for wrongdoing, the same was true for Suji, yet there were quite a few people who defended her; in Jahyeok's case, however, it is treated solely as a personality issue. When he refused to exercise, he didn't say he didn't want to do it but asked if he could do something else. This shows that he isn't hiding his refusal; rather, he has been rejected hundreds of times and learned that it is meaningless. In that situation, there is nothing a child can do once the parents make a decision. He might have been able to speak to Jiyu, but the only form of communication Jahyeok has ever practiced and learned is listening and following unilaterally, so that is essentially the only way he knows how to communicate. In fact, considering he has lived surrounded by such people his whole life, the fact that he doesn't usually show it and recognizes the problem so quickly actually means he is growing up well
I don’t have fast pass for Korean webtoon, but from the cover of chapter 155 I think the Jaehyeok might be featured (probably seeing Jayu’s number no longer in service and he looked heavily depressed). But yeah, everytime I check the comments on the free chapters OOMPH the Koreans are MAD at jaehyeok and don’t even want to see him. any mention of him gets downvoted
