Kanna SATOU
Kanna Satou is a 27-year-old woman who works as an office lady. She is a kind and gentle person, but she can also be quite shy. She has been in love with her coworker, Izumi Sena, for many years, but she has never been able to tell him how she feels. One day, Izumi's younger brother, Ren, comes to visit him and Kanna. Ren is a very outgoing and flirtatious person, and he quickly develops a crush on Kanna. Kanna is initially taken aback by Ren's advances, but she eventually starts to fall for him as well. However, she knows that she can never be with him because he is her boss's brother.
One day, Kanna and Ren are working late at the office when they are caught in a thunderstorm. They run to the nearest shelter, which happens to be a love hotel. They are forced to share a room, and they end up spending the night together. The next morning, Kanna is mortified by what happened, but Ren assures her that he doesn't think anything of it.
Kanna and Ren continue to see each other, and they eventually start dating. Kanna is happy to finally be with the man she loves,
