Examples I could write right away:
The assassin.
Baek Sr's plan.
Not really necessary though.
Saehun's relationship with Seju's mom.
Necessary.
But why do you think if it's Sumin x Sungji, then they won't need to fill all these plotholes?
She's not thinking about Seju anymore though.
Why? Is it because Sungji left her or because Seju has been out of her sight?
Sumin and Sungji are the logical pairing that was built for the entire story.
Who said that?
This last drama is made for them to end together, even if we stopped seeing them as a healthy couple because of what Sungji did.
Unless Sungji is horny again, I don't know how they can make up.
sia ue can you explain why SuminxSungji makes no sense to you? (genuinely curious)
Why crying at home and waiting for Sungji? Is it too hard to find where Sungji is? She financially depends on her family, how far can she ran away from Sumin? It makes sense to me if the person Sumin is missing is Seju.
