Sumin can't do that. Sungji was her last chance. She could always try and start over with Seju so...
Just because Sungji has no chance with Sumin anymore, so you don't want Sumin to be happy with Seju as well?
Omooooo ╮(￣▽￣)╭
Thats not it, i actually prefer seju and sumin together. However, think about it this way, seju will forever feel like a second choice because sumin only agreeed to go back together because of sungji dumping her. That insecurity wont leave. So yea, as much as it hurt me, they all just need a fresh start.
But we still don't know yet, who is Sumin's true love, actually. How if after Sungji and Seju left her, she recognizes, who is actually, the one she has a crush with?
You know what i want????? I want everyone to find a new partner and move on! I cant take this anymore fuck it!
