In 2107 - uke is seme's assistant. Seme has OCD , hate people , just has robots at his house and uke just a property to try his sex toys made.
Uke so in love with him so he cannt refuse being a trying rAbbit.
Seme doesnt touch him and he feel sad bcause he's just used not being love bcause of seme's OCD who cannt deal with touching pepople.
But it ends nicely both them.
