I love this manhwa so much for so many reasons, but the main reason is because it's realistic.
Sumin's first love didn't work out in the end, but she fell in love again and moved on. This happens in real life more often than you'd imagine.
Baek Seju still have to move on; but it's okay, she's on her way to do that. She was petty and possessive and she even lowered herself to be just a sex partner as long as she was by Sumin's side.
It's sad and I have done that out of love, too (or my distorted vision of my feelings for that person).
As much as I think it is bittersweet to explore Sumin/Seju past, I think it is also important because they spent years together and these years molded who they are right now. They were there for each other, and during years they were the most important person for each other. Exploring these memories can make us see that, in the end, they shouldn't be painful, but cherished; departing from someone's life is something that can happen and instead of being bitter about it, you can look back to the happy moments and be grateful you had the chance to live them.

I'm excited for the second season. Jaeha's story is very vague and even though he opened himself a little bit more in the last 10 chapters, it is still hard to make up what he is thinking and feeling.
We don't know what happened with Hyesun and it does play a big part on how he deals with the love he receives from Eunho. I really hope the author tell us more about Jaeha so we can decide whether he is being reasonable or not; if he needs help or not; if it is something he needs to settle down alone or together with someone (not Eunho specifically, but a friend, a relative, a professional).

I think I understand Jun, though. He really understands Shiwoo and Myung are two different people, but he can't bring himself to tell Shiwoo that since Shiwoo never asks about it and doesn't give Jun an opening for him to do so.
The person who is stuck in Myung is, in fact, Shiwoo; he doesn't ask Jun about it and just assume he is a replacement. There is space for a long story, but I hope the development isn't as slow anymore since some drama just started hehe.
THE PLOT TWIST GOT ME LIKE *falls off chair*
Me tooooo. Totally didn't see that coming. I just thought Pinkie was being a douche-bag. Well, I still think he's being a douche-bag.
