Amiri and Sumire were childhood friends. However, after becoming estranged, they ended up in the same school again and reunited, only to find that Amiri had become a delinquent gal involved with semi-criminals and doing drugs. On the other hand, Sumire started dating a guy, but immediately, Amiri began bullying him. In reality, Amiri had distanced herself from Sumire and gone astray because she couldn't give up her unrequited feelings for her. Unable to endure Sumire repeatedly blaming herself, Amiri decided to use an aphrodisiac obtained through back channels to mess everything up.
