If you read carefully, this manhwa itself is too dark, full of rape, sexual harrassment, commting suicide, cruelty, death execution, etc, but sorry, i laught my ass off ヽ༼◉ل◉༽ノ
Like this jerk in ch.1 is the 1st clue, after that, mc was indifferent, just cheered him up and watched from afar until he died, and some info about other crazy jerks that fall for him she mentioned as well. They didnt mention directly, but only a few panel like this one made me guess what he had been through to commit suicide many times when mc is not around.

Everything seems cliche and too easy. All target just fall for mc easily.
Almost all 7 chapters, there will be a special event that let mc respond with oh so good girl and cheesy line, then all that target fall for her (〜 ̄△ ̄)〜that is quite boring
