Forbidden relationship with my best friend's girlfriend... I couldn't stand the attractive body approaching in front of me... "It would be terrible if this relationship came out..." I used her aggressive invitation as an excuse to justify her cheating on her best friend's bed. I was greedy.In her guilt, there is myself who is proud of Aika's face who looks like she is comfortable while despising herself for her best friend's girlfriend.No one knows what will happen...
