The majority of ships I don't ship in K-dramas, end up becoming cannon.
Which really sucks because you can predict the ending.
Thus, making the show boring since you know how it's likely to end imo.
A great example is the K-drama called My Lovable Girl.
I really want the heroine to end up with another guy, but she can't let go of her first love.
Thus, her and her first love get together, and that's the end.
I'm on the second last episode, and that's how I predict it's going to end.
Kinda disappointing, if you ask me.
