It's only fair and logistic that if the author has chosen SuminxSungji as endgame then Seju would get her own side story.

No matter how much haters she has gotten, objective readers cant deny that her character deserves more than that and it would be a shame to see a sad and lonely Seju even when wdtfs has ended. She deserves a story on her own.

My question is how could you build a story about her without ruining the image readers have about her? An image that I think most of Seju fans dont want to be ruined.

Drama, there would be alot of dramas even without a proper third character's appearance (Sumin) but what kind of path the author will develop for this side story? Since wdtfs is already a cliche story, I can only think of this

• Build her an ambiguous relationship with another girl, no proper title for their relationship, using each other to satisfy each other like Seju used to do that with Sumin. And then one girl fall in love in that relationship (pretty sure the new girl will be that one) and drama begins

• Right from the start, one girl already falls in love with Seju but Seju doesnt(?). She doesnt want anything to do with love or anyone. And the girl would have to work hard to earn Seju's love. With this scenario, Sumin's appearance later of the side story will get us some more dramas.

Any other suggestions for which path could Seju's story be? And out of the two possibilities, which one do you think is better?

But seriously, in whatever cases, the new girl would always be the one who fall hard in love with Seju first, I would be very very surprised if Seju could love a new girl so easily.
