Koi Dekinai no wa Kimi no Sei

Reiichi Miyoshi is a jazz musician who avoids long-term romantic relationships, opting instead for casual and fleeting encounters. One day, he intervenes to help a person being harassed by a group of men, only to discover that the individual is Sara Aogiri, a crossdresser. Sara is intent on capturing Miyoshi's attention and keeping him exclusively, despite his reluctance to commit. Miyoshi remains resistant to the idea of a serious relationship unless convinced otherwise.
