I actually hate this story now. I've seen the raws and ML is gaslighting MC saying that he is marrying that other guy for him. He is planning to keep MC as his side bitch while having an official husband. However, he also told MC that he can’t be with anybody else because he doesn’t have a hobby of sharing his possession. MC accepted this and now they are fucking.
You all must be kidding, MC is just pretending to be a high schooler. He’s hundreds of years old and ML knows he’s old af nearly from the beginning
