Such a lovely comment!!
I personally never saw Seju as the enemy/antagonist of WDTFS story (despite the fact that she pays the role of an ex), but it's definitely great that a character who, after all, got the short end of a stick gets her own ark and a chance to be happy cause, just like you said, she really deserves it after what she's been through
I think Team Gaji did a really good job by showing Seju as a complex character and not as a simple "villain" or something of the sort. I truly appreciated that this story didn't feel stereotyped and shallow in anyway. I loved all the 3 girls (and I still do) and suffered with them anytime they had problems, or felt betrayed. I think it is difficult to create 3 sympathetic beautiful characters in a romance genre story as Team Gaji did.
I really want everyone to have a sweet and nice happy life, like seju, I really want her happy I love that sumin and sungji are living together and I know seju was the enemy for most of the manhwa but I think she deserves to be happy after all that pain, I wanna see that kiddo smile again I want her to be able to love again and that last chapter (110) gave me hope, best wishes to all the lovely characters of wdtfs fighting for a happy ending
