"murderer llewellyn's enchanting dinner invitation"; it's the peakest peak of all time, and has an amazing plot. it's hella intense though.
if that's not your taste, i'd recommend "heesu in class 2". it's super cute and sweet, not toxic at all, and has lovely characters. a similar rec would be "the story about you x me" it's VERY underrated.
