Story
Biwa, a 26-year-old office worker who is well respected within her company, thinks it's cool to be a girl who can live on her own, but she really wants to be spoiled by someone! She was so pampered by a persistent pick-up girl that she decided to help her out. She gets tangled up with a persistent pick-up artist, and falls in love with the man who saves her. When she goes to work the next day, she finds that Tanaka, a junior colleague who has been assigned as her mentor, is the one she never expected to meet! And he's a very salt-of-the-earth guy who doesn't like women!
