A) Not listed . Random . Not read

Spoiler 1
Mc is not in love with them (set in stone)
Spoiler 2
I read the novel and Yesseo will end up being Cedric and Chris’s spiritual partner. So the end game will be 3p where Cedric will have kid with Yesseo and so Chris with Yesseo will have a kid too. Cedric x Yesseo x Chris. For the romance, I’ll leave that at your imagination how you see them. For me both of Cedric and Chris is in love with Yesseo for sure.
