Asahi Hiiragi offers to help Uzuki overcome her severe shyness, but she's horrified by the suggestion. Uzuki's introverted personality leads her to work as a cleaner, where she doesn't need to interact with others. One day, Asahi asks her on a date and confesses his love for her. As a towering and stoic security employee, Uzuki finds him intimidating, but she becomes more comfortable when she realizes how patient he is with her. Despite her reservations, Asahi suggests a "trial period" to continue their relationship, and to help her face her fears, he even bares his muscular chest. This is a beautiful love story between a reserved woman and a candid, serious gentleman, unlikely partners who find love.
