Ryuusei Koike

Ageha's childhood friend from when she lived in the countryside. He's considered good looking, and is a nice, outgoing person. He is a bit clueless when it comes to the rivalry between Ageha and Hana, as he sees Ageha as a good friend. She had a crush on him since they were kids, but because of her appearance she never felt she was worthy to go out with him. However, after her appearance change, her sister Hana quickly steals him away before Ageha could confess her feelings to him. He was dating Hana, but they broke up because of Hana selfishly requesting his time at the drop of a hat and especially after she disguise herself as Ageha to see if he would be faithful to Hana. He later reveals to a disguised Hana that his first love was Ageha, and he would have dated her if she asked him out.
