Yeah like I’m gonna be honest it really comes down to a lack of critical thought. Like the author wasn’t subtle about it and Wonwoo’s inner monologue has even hinted at this multiple times.
Taeshin is a true true Yandere. He’s obsessively in love to the point that he’s become sick from it. I’m living for it tbh, I love a by-the-book Yandere and as long as he doesn’t end up abusing or raping Wonwoo in the coming chapters I think this will be pretty great.

So many readers genuinely didn't see this coming and in a completely nonjudgemental way "howww?". Fully expected this at some point, based on things he'd say in the first few chps.
Honestly it's been quite well done... the author took a different route with a trope that is overused, usually in poor taste and imo very boring.
Clearly their approach worked in subverting expectations, because alot of people are in complete shock T_T.
Also ik its crazy to say but to be completely honest Taeshin's obsessed is so freakin gentle, he's genuinely saying "im gonna love you so fucking much" therefore you cannot leave me,, it's a questionable but freshish take on the "possessive boyfriend" note how he's doing all of this but there’s no violence, the lighting never changes. It's still fricking sunlight and cherry blossoms lmaooo.
