Just caught up, and I must say I've liked it more than it should deserve. It's a bit childlish and some plot points feel way too forced, but it grew on me thanks to Hamin somewhat.
Now, I could be proved wrong (and that'd be fine too), but it seems quite clear to me which ships will sail:
1) MC's girl will be Hamin, I mean (pun intended): she's the only one to have shown romantic interest in him (I refuse to take Sungah's "crush" seriously), and she's the only one to still have a backstory in store (well, except Sungah's awol friend, who I'm quite curious about, in fact).
2) Yuri'll probably have her way with her old crush, since we're spending so much time and effort redeeming him. She's never seen MC as anything more than a friend 'til now, and, while this could change, it just seems unlikely.
3) I don't know about Sungah. Maybe she'll end up with class rep in a few arcs' time, after working as romantic foil for MC and Hamin; maybe she'll end up alone, or - that would be hilarious - with MC's sculpture friend. I don't really care about her.
4) Lila's gonna redeem herself, at most: MC doesn't seem to be interested in her at all, she isn't even in the race.
