Yoriko is an honest, hardworking woman who somehow reunites with her high school clubmate Yutaka after transferring to a new company. Yutaka's known around the office as a charmer, but he's pretty quiet and seems a little different from others. One day, he comes out to Yoriko and says she was his first crush! Of course it looks like he still really likes her too! Yoriko is happy to hear this, but Yoriko just has one issue... she's a sex freak and it pushes away most guys. However, Yutaka only has one thing to say: "That's awesome..." Now they're going to try out things in bed?!
