Atsuro is rich turned poor, and he wanted to go to a concert and the MC (seme) offered him tickets, and in exchange took advantage of him and now Atsuro is locked up with no way out. The MC is insane thinking as far as killing Atsuro with a knife and even has funds to escape but he knows Atsuro won't be able to escape because Atsuro is traumatised.

The smut is just r*pe again, the uke has chastity cage and it's even implied that the seme broke the uke. And the seme cried because the uke will not be the same or come back to him wtf lol

It's just plain sad even for a one shot, the smut's not that great to overlook the r*pe and abuse going on. Btw it's the seme's pov.
