Ahahaha lol bless the kids who misread this as Doraemon
Till now: Seong-Ho is conflicted because he's desperate for his feelings to reciprocate from Na-Kyum whereas Na-Kyum still can't let go of In-Hun because he regrets his present now, still thinking he's forced and tends to say sorry rather than noticing senpai's feelings lol and so Seong-Ho's going to make the wrong choice now...
But I think they'll end up together in the end, moving on from past.
Manhwakas finding out mangago and declaring wars lolol
Just meh
Gotta give kudos to the sly dude for at least clearing things up (both in the story and beyond the 4th wall)
