Can androids fall in love? That is what Nat thought to himself.

One day, an android (humanoid robot whose appearance almost like human) arrived at An's house, called himself "NAT-39" and said she is his new master. With a face similar with someone who was special to An's, she let the android stay in her house. As time passed by the android began to learn about An's life, about the certain someone... and so about himself.
