@Dykejiah I don't know,that seems more of a real life thing. In nearly every manga and manhwa I've seen, the persistent suitor trope was still played off as cute/comedic when it was a male character. With the exception of like, drama/thriller manga.
Either way it doesn't bother me as much here, mostly because he hasn't actually rejected her yet, just thinks she's not serious (not that it's not still weird, just less annoying to read)
