Kind of a weird way to end the Arc, but it's ok cause I like Hooni better than Sana. I do hope that Sana's crush on Soorim stays as a regular thing tho, I'm a little tired of all the arcs meaning nothing to the story overall. Even the "Suicide Boy Arc" was meaningless in the end.
Anyway, author. You already set Sana>Soorim, so Hooni>Soorim wouldn't hurt anyone, right? /s
