Overview
I'm an office lady, and a part-time rental girlfriend. I'm good at getting along with people and can do anything. I'm not particularly interested in romance right now, but I imagine I'll get married and have kids someday... Then I met Sui-chan, my first rental girlfriend client. At first, I was hesitant because we're the same sex and she's younger than me... but then I thought, wow, I'm good with women too!? (Source: Ichijinsha, translated)
