Hinano-chan, who lives in the room across the hall. I've always thought she was cute. One day, when I opened the apartment door, Hinano-chan was peeing herself in the hallway. It seems she forgot her house key. Thinking it was a great opportunity, I invited Hinano-chan into my house. Although she was wary at first, Hinano-chan gradually opened up and started showing me her smile. I guess we really understood each other's feelings. There's no choice but to get married. This is a commemorative video taken on the day Hinano-chan and I had sex for the first time.
