Mami Nanami

Mami is Kazuya's former girlfriend and a current student at Nerima University. She projects an image of innocent charm and approachability, but beneath that polished exterior lies a calculating personality who fundamentally doubts the value of love. Although she was the one who ended their relationship, she couldn't stomach seeing Kazuya quickly move on with Chizuru. Consumed by jealousy, she repeatedly interferes in their relationship under the guise of friendly concern, while venting her true feelings through a private social media account. Her actions serve as a key catalyst for much of the drama throughout the series.
