Rei Sagami

Serving as Sana's devoted manager, this character finds himself at the center of a complicated, one-sided romance. Though Sana mistakenly labels him with a provocative title and views him as her boyfriend, Akito and Misako eventually reveal the harsh reality that Rei is merely acting as a guardian to a child. Despite the heartbreak caused by this realization, their bond eventually evolves into a stable, lasting friendship rooted in professional support and mutual care.
