Ayumi honestly needs to see a therapist lol.
The step brother needs to be in fucking jail.
Ayumi is atleast better since he didn't actually permanently chained the uke and actually gave him all of the shits he needs, wants, and he loves (or obsessed) him truly.
4 stars still since the ending was cute.
Ayumi and step brother needs to go to the therapist but the stepbro need to go to the mental hospital aswell
