Don't feel bad. There is a reason some webtoons/mangas/manwha's, etc., come with trigger warnings. Some characters are just WAY too realistic and some plots just hit WAY too close to home reality-wise. The stalker is definitely one of those. Every time I see him, I am reminded of a young actress from an 80's TV show called My Sister Sam. She had a stalker that eventually showed up at her door. She talked to him for a brief moment and he left, only to come back a little later and shoot her dead on her doorstep. She had thought he seemed nice and never realized that he was a serious threat to her life.
And don't get me started on the creepy Bjork internet stalker that killed himself after he mailed a bomb to her. Luckily, he was found and they discovered the info on the bomb package in time to stop it from being delivered to her. *shivers* Some people are just insane....
Even though ik this is a webtoon but there are ppl like that irl .. LIKE WHO RAISED YALL TO BE LIKE THAT MAN ? why do they be so obsess.. idols cant even be themselves without someone in they business.. like whats the point of being a stalker
