Summary
Yamamoto Jun, born on February 14 with AB blood type, is Megumi’s brother. While he generally presents himself as a pleasant individual, little is known about his background. A peculiar trait defines his personality: when kissed by a girl or when intense romantic affection is involved, he undergoes a split personality shift, transforming into a bad boy. Despite dating Sakura, he also exhibits a strange attachment to Ryuu. He is currently a third-year student in high school.
