Love Is Indivisible by Twins: Rumi Jinguuji

 She is Naori's sister and Jun's ex-girlfriend. The heroine of this work. Jun's childhood friend and fraternal twin sister. She is a member of the women's basketball team. Bright and active sports girl. Short hair. Before she started playing basketball, she tied it in a ponytail. Is characterized by a mole at the mouth. Slender figure. She is the type of person who participates in class events with all his might but does not perform well academically. I like my classmate Jun who lives in the house next door, and I confess when I was in the third year of junior high school because I was impatient with the relationship.
