I think that the accident was a little too much... Haesoo was already made up about his feelings and their situation, so the accident makes his confesion a bit forced. And I don't like that. He finally maned up, but his efforts and sincerness was ruined by this action ( ̄へ ̄)
Though I'm glad something happened finally.
I'm not okay with a lot in this story, but if you don't overthink it, it's quite lovely. I think the author just isn't educated enough and that's okay. No hate
