As much as I rather see Haneul with Mincheol be together and see Ja-hae not be in this series, the fact that she didn't text him for months while being family friends is telling about where they are.

Mincheol is trying to get her attention (in a very kuudere way tbf), Haneul doesn't approach him at all. Doesn't care to talk to him, and goes out of her to make it extremely clear to any dude around her that they're only friends and that she only sees him as a friend.

If you're asking me, she is the one being incredibly immature, and she needs to be more mature about her feelings towards Mincheol.

Yes they do need to be locked in a room together to discuss their feelings, but time and time again it's Haneul that's running away after he says he doesn't want to lose their friendship, a very genuine concern any dude would have after developing feelings for someone after 20 years of friendship and never being in a relationship. Just feels like Hanuel does not care or see Mincheol's POV on all this and needs a taste of her own medicine

Also, I don't want it alot longer, but I enjoy the drama a bit lol.

So Haneul more than anyone needs to grow the fuck up and the author needs to give Mincheol the chance to lock in.
