Like I understand the reasoning like how a lot bunch manga using bullying or reality-escaping as some "normalize" trope because that what their reality in the society so they have more idea, experience, history, and/or opinion on it? Like bunch of Asian medias has patriarchy theme because ... its what we daily see around? Kinda hard to explain it. Using the theme probably not in offensive way like u said. But I dont think u are sensitive, its more like we have different view on this because for u its like someone from normal household looking at some weird behaviour from someone that life in broken household.
Ah. Im sorry for ur family. The same for me too so I assume ur case is like some judgement that I got sometimes for my weird habit.
Ayy. Thats okay. Some trope is not ur cup of tea. I dont like OP mc and gore for example. Its not about u being sensitive. Everyone has their own boundary. I hope u get another stories to gushing about. We have plenty here!

Or do korea really just be making fun of suicide. Like not everyone has to kill themselves. I get it's normal for them. But its really insensitive to make a main character change because of suicide. Or of someone death. Maybe im too sensitive
