Does anybody know which vol is this? I'm trying to find it in the novel

Holy characters development

MAYN HE'S GOT A RATIO OF (TOP) 3:1 (BOTTOM)

I couldn't read any other 'shallow' and 'tacky' bl plot after reading this one. Every character have their own depth and story whick makes it a whole lot interesting. I'm definitely reading the novel once my semester end!
