Aoyama Saori, working as an office lady at an MNC, gets into trouble with a drunkard on a train. She's saved by Yamada Tsuyoshi. As a form of appreciation, she sends him Hermes teacups. Having no experience with the opposite sex, Tsuyoshi decides to ask for help on the Aladdin Channel BBS on how to interact with Saori.
