Bro im confusion

This needs s2 or side stories there's so many that was missed. At the last chapter yeonwoo was feeling dizzy again. That needs to be clear, even some issues before they got together, what was that cult about and why do they want to kill keith and who's the mastermind behind it. I think it only focused on their lovelife more than the whole story itself. It's like those complications and problems, aside from the both mcs being dumb, are just to add a lil bit of spice but it turns out not being that necessary. I feel really confused about the ending. And i can still feel that yeonwoo and keith's relationship still has toxicness that they haven't resolved yet. I just hope to get this many things cleared but if that's that. Then that's all we can accept and just continue supporting it and the author as well.
