Rejected way too many times żeby good-looking (and unattainable) guys, shy Riiko Izawa goes online and signs up for a free trial of a mysterious Nightly Lover 'figure'. The very next day, a cute naked guy is delivered to her door, and he wants to be her boyfriend! Riiko needs money after giving all she had to help pay for Night, so she finds a job at the same place Soshi works. Not wanting Night to worry, she doesn't tell him about her new job, but Night finds out anyway. What's even more worrying to Night is how Riiko is beginning to feel for Soshi.
