I Married My Best Friend to Shut My Parents Up

Morimoto, a young professional woman in Japan, is tired of fending off her parents' questions about her being single. They want her to marry a man and settle down, and they'll insist on nitpicking her choice of groom to death. In an unexpected move, another woman in the office - who has a crush on her - offers to be her wife in a sham marriage, which might make her parents back off. But this "fake" marriage could unearth something very real! Note: Includes the extra chapters "Anaerobic Love" and "Fake Married Life".
