Who do you think is the end here? 

Honestly I think for me there are literally 0 surprises it will be Bani and Jaeyeol 100%. I know kdrama well and it's always like that. The 1ML always ends with the FL, I doubt it'll be like "Love Alarm" where she chooses the 2ML. Here either he sticks to the webtoon or she ends up with Jaeyeol. For me it'll be him of course!

DEFINITELY hwang jaeyeol. she's the only guy she liked (kinda jo arang but not much and she used to like jin hyeono but jo arang is a bad person and hyeono gets no screen time so it can't be him) she only ever saw jiwon as a friend and his whole character is pure second lead vibes. also I think the relationship he has with his sister is a bit weird... everyone in the school apart from their friends ship bani and jiwon is jiwon is popular and rich ig, but her being with jaeyeol is kinda like dramatic irony and it hints that she will stay with him bcs usually the fl goes against the majority's opinion. the whole story is basically solely based on them and the show's cover image is even those 2. Has to be yeol
