then do you know who will end up?

From what I read, that is the plan. Who knows if it will go down that way as we're what ten chapters from that anyways at this point? Still, it is the plan.
No. I have no idea how it will end up. This was what the author said on Twitter according to the screen cap I saw.
I just hope we don't end up with no first kiss for our MC, and yeah, I'm team Junseo all the way as end game. I can see side stories emerging after the comic ends as well if things aren't wrapped up properly with all of the characters.

Do you know the author’s twitter handle?? If so, could you please let me know what it is?

Nvm did a lot of digging and I found it
There is a rumor that this ends at 172? Geez, there's so much more story to tell here, but I hope it's not rushed and ruined after doing such a great job thus far.
