Yea like, that's SO WEIRD MANNN! THEY HAVE A 6 YEAR AGE GAP. And I'm usually fine with big age gaps but the circumstances of this one are SO uncomfortable. He was deadass a minor!!! It should've been one-sided on his part for years and THEN she starts liking him. I would've been kinda alright with that.
It was also mentioned that he was a minor at the time and only had about a year left before becoming an adult. That’s why he asked her to give him some time so she could accept his feelings. And last I checked, 17 is basically the final stage before adulthood in Korea, and even 18 still feels a bit icky, because only the age changes, not the level of mental or emotional development at that point

This is giving me the ick, esp with teachers engaging in relations w kids being rampant nowadays. It was cute at first until mc decided to basically fall in love w a minor and stalk him. Wouldve been a cute trope if mc fell for ml when theyre finally both adults, and ml is out of school. Not when ml's practically a kid and barely a few yrs after hs. I feel like she's just coming off creepy now
