Looks-obsessed, flippant attitude towards partners, demands his partner changes to fit his taste and cares more about sex than personality. All traits I can't stand yet I just can't hate the ML. He's trash, but he's recyclable trash. An a*hole who is, in his own way, trying his best to have a good relationship. A garbage foundation with a good work mentality. He's got bad priorities, but he puts in serious thought/effort and is willing to change/learn.
One of the things I love about this manwha is how many of the standard tropes have been avoided/switched up.
One example is how so often we have a female lead surrounded by guys in love with her and with only her maid as a close female character. Here she is surrounded by gals and it's her servant who is a guy. Plus the guy isn't romantically interested in her. It's just nice to see a fl with proper friends and not just friendzoned guys.
