I'm going back home, the connection is good so I'll share my thoughts now, before you produce another 100 pages. I've written them right after I've read both chapters and edited a bit after reading you girls here and checking some things up.
First things first, what surprised me:
1) Seju blew up and ran away.
2) Seju had really blew up. Or at least it really looks like it.
I was not expecting her yelling at Sumin at all and the first thing I thought when she walked out of that apartment was - ok, she's in her game again. But then it didn't look like she wanted to go back. If Sungji didn't walk into her, I don't know what could've happened. But... I think Seju overreacted a lot. It was a simple question to which she could've simply answer instead of making a scene...
Gotta say Sungji and her sister in-law can eat a lot. A whole cake? I'd like to see Sumin doing something similar (she's going to do all the eating, right? :P).
I'm more than ever convinced the end will be Sumin with Sungji. It's nearly impossible for Sumin to go back to Seju. I can't see her breaking up with Sungji and I can't see her moving on if Sungji breaks up with her again. Those little hearts when she saw Sungji left a perfect mark with a lipstick... Aww. Then we have what Sungji told Seju - "there's a family that believes in me. And friends. And Team Leader Nim. I'm not alone." She's not giving up. What she told Seju looks more like an advise IMO. That maybe she should consider leaving to end or at least ease the pain she's in. And the last one... Sumin forgot about Seju's birthday. If you love someone, really care for them, want them to be happy, you never forget things like birthdays. Especially in Asian culture and when you have literally nothing to do because you don't work. So there's no excuse for Sumin forgetting about it. She did because she's completely fallen for Sungji and Sungji is the only thing Sumin sees right now.
It was great to see Sungji knows everything about Seju's situation. It's clear she and Sumin talk about stuff rather than leave it in secrecy. Too bad we've never seen it though.
What I wish to see now is all 3 talk to each other, find a way to deal with this situation. For Seju to be happy whatever happens and I wish for her to decide it. If my feelings are right and the end isn't for her and Sumin then I want Seju to make this decision - let go, tell them she wish them happiness etc. I also want her to remain friends with the other two, but after what Sungji said, I think if she'll really chose to let go, she'll leave their lives. At least for some time, to deal with her own feelings.
I also want to know what's going on with the assassin. Is TG dealing with her behind the scenes?
Nora, I know what you're gonna say - it's not over until it's over. So I'll use my personal fav - Seju doesn't need Sumin to be happy :) And with this, I'll say that if Seju ends up with Sumin it'll mean TG lied.
I disagree about the "win" part of Sungji's talk to Seju. Someone on 4chan said that it's an idiom, has nothing to do with winning or losing and is used when someone doesn't want do to another person a favour, but does it anyway because that person begged for it. I'd copy it, but somehow I can't...
As for depression - it's not always a choice. Usually it's not and it's because of the hormonal changes in the brain. If your brain can't function properly, you won't be able to choose better.
Sorry if there are any mistakes, I'm using mobile and autocorrection can suck from time to time. Especially with swift keyboard using flow.
