The seme was hella possessive, basically he found the uke was a werewolf and kidnapped him. The seme is a vampire, but he loved the uke’s blood. This lead to the uke being shackled with a leach until the seme determined that the uke loved him too much to run away. The love can be considered Stockholm syndrome in my opinion. The uke could have fallen in love with the seme normally but the vampire did force things. Trigger warning I considered it rape when the uke had his eastres period and the vampire decided to help with his heat by being his partner instead of allowing the uke to copulate with a female and he wanted to.
I still read it and found it interesting, translation was a bit confusing but thanks to the translator for their hard work. May not be everyone’s taste but it suited mine.
