Turned out to be less f'd up than I expected from the title? Initially, Ryu-chan was going to be sold as a "pet" to some random dude which could've been this middle aged man with some small d and weird fetish. But instead, his "friends" who were going to set him up for the auction decided "nah we don't know what those people will do to you so be our pet instead." Which in hindsight is still a bit f'd up but hey at least they treat him well with care (and they got his bro covered with the medical fees). The BDSM for this one is honestly pretty hot, it's hard to see proper S&M relationships in BL so this is a nice addition to things that I can tolerate to read.
he was a slaved but his masters are the people who he considered as good people on his childhood. Nice cuz it's just like sub and dom + there's no abused, they're pretty good
