I am team Seju and only Seju. I don't stand on any boat now cos I don't like Sumin. If I still had any little hope of SejuxSumin, it is because that foolish Sumin-obsessed Seju still wants Sumin. My opinion of Sumin changed a little when she said she felt guilty treating Seju like that, but not enough to like her. Her attitude towards all her girlfriends is problematic. Her taking things for granted to that level is unacceptable. Her feeling uncomfortable when Sungji is close to Choi gun and at the same period feeling angry when Nami bedded Seju is... I have no words for it. I know Sumin should changed for the better by the end of the story, but SejuxSumin is more difficult to write than SungjixSumin. It is strange for Seju and Sumin to get back together without a phase in between. They have been in an unhealthy relationship for too long to jump out of it immediately. I hope the ending for Seju is that she walks away from Sumin and learns how to protect herself and her love ones from her psychotic brother and fake family.
