Kazuha Akiyoshi is the eldest of six children. Highly responsible and irresistibly cute, she is also something of a tomboy who never allows her softer side to show through –– until she meets Mizushima, the first guy to treat her like a girl. Mizushima was her first real crush; will it be reciprocated? Then there’s Sugimoto, an older guy who wants to be an important part of her life — but he’s the one who Kazuha hates more than anyone!
