I really don't want that red head as ML, I mean he killed the MC's "parent"? In the recent manhwa (ch 9?), I can't read Korean, but I could get an idea that the red head was jealous of the blond chef because MC blush when he make a move on her. He also secretly learn to make cherry dessert for the MC because she liked it. But come on Man, he killed her parents, I don't think he deserved to be loved by our MC.
Anyway any spoilers?
