What I hate is that I know this author is going to try and justify this abuse. That's kind of their whole thing, lol... I shouldn't blame this author, it's kind of the theme of all toxic seme yaoi manhwa.
Just let the toxic seme just be toxic. Don't try to justify it through childhood abuse or whatever. No one thinks being abused as a child excuses you to abuse other people as an adult. It just doesn't accomplish what the author wants it to accomplish, which is the audience thinking a future where the two of them live happily ever after is possible when we know one of them is wildly, almost cartoonishly, abusive.
