Spoilers . . . . .. ... ..... ...... ....... ........ ....... ...... ..... .... ... .. . . . . they're not technically related, Aria's dad got kicked out because he was a bastard, mother had him out of wedlock if i remember correctly
I feel like the Romance part was forced or more like rushed they didn't have any chemistry and he didn't pay any attention to her romantically before what changed now plus wouldn't you want to spend your time with your family and mother who woke up from coma?
I do agree with you if you only have read the webtoon, in the novel there is a slow progression to the date as well as before and even after the date but in the webtoon it’s def rashed, the romance also is more adressed after the main story is over
What if they sold ointment in a smaller container?
