I want Seju to be all alone without any connections with Sumin first, sth else later. She has been too dependant on Sumin, and honestly, I don't like that fact. But I wish the conversation hasn't made to sound pretty selfish on Sumin's part :) (she wants to find love for herself, etc), that would've been nice.
You are right, Seju should be alone for the moment. She does not know her value as a person and she needs to learn it.
Also, I hope it will be a quiet farewell, not a messy cheating. I'm praying so hard next chap will not be sex :). Cheating is the worst thing happened for a relationship. I know that with this story, somewhere in the future, it's totally possible that Sungji might get hurt, but hurt by cheating is just too cruel. This story is already too cruel for Seju already, hope there will be no other victim :). Plus, if Sungji could easily forgive Sumin for this, I'll seriously go "Are you even a human?" to Sungji, cheating is definitely not some kind of silly argument, you'll probably completely lose your trust for your partner which is never easy to build back.
I think that do not matter what team you could are... Many people think that they cannot have sex together. Because, that action would mean hypocrisy by Sumin, specially when that was the reason she decided not to stay more with Seju when they had a relationship.
I know that Sumin is confused, she have never been able to be without Seju but she took her decision, it is time to be strong and confront it.
the good things about Nami. XD
Nami is so cool. I like her dialogues because she is funny but also she is direct and says what she thinks.
This is a character necessary for this story, if you see, she is who has the feet on the ground, she is the only who tries Sumin and Seju are honest with themselves.
Although, sometimes I feel like she is Sumin´s friend only for to be close of Seju. Then I remember Sumin and her are good friends..........
