Seriously, I'm not into mafia things too.. But, he's not like any other mafia! He seriously never opt to hurt his partner(in bed). Just look at how long he's waited to be in bed with Yoon. If he's really a bad guy, he would have raped him sooner. He only did it after he knew he's fallen for Yoon and even after Yoon became accepting of him. And I love how the story shows even a mafia falls terribly in love. And the way he would show up to save Yoon every time is what makes me loves this manhwa even more!

Yul is actually a depressing character. I mean, he didn't get enough love from his mom, being rejected by his teacher, when she even had to choose his uncle at that. All while Yul is actually a super kind person! I know I shouldn't but I've been rooting for him since they ended up waking up in the same bed! I really need a prequel for him. I want to seem him happy with his lover too.. Because he's a nice kid really.. Uwaaa.. My baby Yul, please be happy in your future.
WHYYY????? I CAN'T BELIEVE HE COULDN'T EVEN WAIT UNTIL MORNING! POOR MY BABY MOMOKI!! AAAAA... I WISH CHIKAGE REALLY REGRETS HIS DECISION AND MAKE A FOOL OF HIMSELF JUST TO GET MOMOKI'S HEART BACK! PLEASE MOMOKI, DON'T FORGIVE HIM EASILY.
