This was what I've been thinking all along. Like, all you did was screw each other without so much as 'Hi! My name is-' and now you care for him? You don't even know the first thing about each other and the 'I-think-I-care-for-him' montage was so obviously forced and unconvincing since they barely did any couple like things together like, oh I dont know, A DATE AND A PROPER CONVERSATION OTHER THAN 'I NEED TO FUCK' AND 'LETS FUCK'? I'm just so pissed at this wasted possible diamond that turned out to be Fools gold. There was so much potential to this plot other than smut driven yaoi. I'd be less angry if it was just any other obviously smut driven yaoi but this gave a promise of possible Father daughter bonding or two dads and daughter bonding after falling for each other.
But no. *insert star wars meme of Obi Wan Kenobi shouting 'You were the chosen one! You were supposed to defeat them, not join them!'*

Vicar was right he shouldn't care for Mc, they just fucked.
