Comment by Peach on Hard-Boiled Love - Chapter 53

For those who didn't understand:

Hwayoung goes to a dungeon and is friend with this 4 other doms who have different preferences during a bdsm play. Originally he wasn't that into piercing play, and so he asked his friend for recommendations and aftercare routine. As a thank you, Hwayoung sets a dinner with him and the other 2 friends. 

Seongjoon (blonde hair guy) is beating around the bush to say Hwayoung should share his amazing sub (as in reference to what they used to do before Hwayoung met Kyuwon: basically rotating subs that are good amongst themselves, since they didn't have a strict relationship with their subs). Seonjoon is jealous of Hwayoung because he gets to have both a good sub and a lover, so he basically spent all chapter provoking Hawyoung for him to loose his temper. But instead of losing his temper, Hwayoung is just very confident now that Gyuwon won't sub for anyone else but him.
