She doesn't want to disappoint anyone, so she throws herself into work. One day, after she agrees to join a mixer out of the blue, she meets chiropractor Sota Kikuchi, who's got her ideal muscular body. She lets her guard down around him. However, Sota kisses her sweetly and gently. He stimulates her in a sensitive spot in a way that she's never known, making her mind go blank just as she's fretting over whether or not to tell him she's never been with anyone...
