The most healthiest couple ever. They only have like 1 somewhat toxic moment and even then it's immediately better the next chapter.
Chi-Hwan (Top) calls Sooin (Bottom) master, he worships him, does whatever Sooin wants, always puts him first and just ughhhhhh. Sooin is super submissive but he becomes more dominant in the side stories which is really nice to see.
Seriously, READ IT. 100/10. I've re-read it like a million times.
(P.S. At the beginning there's this a**hole who's really abusive towards Sooin but he's dealt with swiftly by Chi-Hwan so don't let that deter you from reading but do keep that in mind if you're sensitive!)
