I have this feeling that yes, that's her reason.

Plus there are some pannels that might show that she's liking Sungji too. Or trying to at least seduce her and break Sumin's heart. Again.

No arranged marriage? I feel a lot better now.

There's no denying that Seju is the biggest mystery of WDTFS

My theories for the plot:
-Seju is getting married
-Sungji and Sumin start dating and they have a rough start but Sumin slowly changes how she sees relationships
-Sumin is falling hard for Sungju but denies it
-Nammi is like "gurl wtf you're so obviously in love with her"
-Stuff happens and they break up
-One of them tries to get another relatioship but its not the same thing
-Lots of misunderstands happen
-They make up and start dating again
-Happy end

we must learn Korean for the next chapters :x

Know the feel. I'm trying to learn through youtube videos and tutorials but it's hard

After a long time stalking this forum I decided to make an account. Yay!

We should bet what's going to happen in the next chapter. I think that Seju is going to cockblock them.
