When Hana finds out that Ageha has a crush on a cute boy named Ryuusei (who is actually Ageha's childhood friend from the countryside), Hana becomes curious about their relationship.

However, after hearing that Ryuusei hates people like Hana, Hana becomes irritated and using her charming personality, actually manages to snag Ryuusei as her boyfriend!
