They should, but it's a comedy/school life romance, so while that one scene where she reveals the pictures are very dark in tone, they only really serve to set up the possible romance with sora's friend and sora's problem, so if anything they probably won't mention it again (especially if the author only used it as a plot device), or mention it in passing and then not bring it up after a sufficiently uncomfortable reaction form one or more of the characters. This tends to be more common in manga, so it might be wrong and it might not happen.
On the other hand, they could go deeper into Jaein's character and sort of do a redemption/romance arc with her friend and have her realise that grades aren't everything and etc. which imo seems most likely since most romcom webtoons go that route where they admit their wrongdoings and move on, but since it's a romcom, she probably won't face actual consequences that impact her too much??
Now I see some people rooting for Jaein or failing to understand as for why people do not like her but really?? Did you forget that she has her room filled with pictures of her, she stalks her throughout the day, is super possessive and literally sees her as a god that should be isolated from the rest..... I don’t want to ship her with anyone
