I'm Tsubasa, a student at an art college. This time, I had to draw a nude man for a school assignment, so I asked my boyfriend to be my model, but he started making advances on me halfway through, so I couldn't finish the assignment... At that time, my brother noticed that I was worried and called out to me. That's right... I was stupid to ask for advice about something like that. My clumsy brother got out of control...
