Summary

Chiyo met Mutsumi in elementary school. Being three years older than him, she takes care of him like an older sister even though they're both all grown up now. However, after she dressed up all nicely for a company party, Mutsumi seemed to react outside of expectations! A raunchy sweet love story between a handsome womanizing artist and an older, meddlesome office lady.
