Third season of Hyakushou Kizoku.

Sae Iwata was never cute or dainty like the other girls, and due to her build and strength, she always felt the need to look after her delicate childhood friend and crush, Kouki Kamishiro. But as years passed, Kouki grew taller and more confident, which resulted in them drifting apart. Toward the end of middle school, Sae reconnects with Kouki. Seeing that Kouki is still the sweet boy she once knew, she realizes that her dormant feelings for him have resurfaced. She tries her best to suppress her emotions—but it becomes even more difficult as, come high school, they end up in the same class. Ignoring her deepening feelings may seem like a fool's errand, but this boy that shines brighter than the sun may just prove to be her destiny.

Azusa Kannawa, ace of the publicity department, is known for her unmatched reliability. Her coworkers, on the other hand, find her no-nonsense demeanor intimidating. Yet, unbeknownst to them, a socially awkward woman hides underneath the facade, simply struggling with casual communication and masking it with a strong attitude. However, her mask begins to crack when a promising rookie, Yuu Kamegawa, joins the team and Azusa gets assigned as his mentor. Determined to guide Kamegawa just like how her senior once trained her, Kannawa puts utmost effort into showing him the ropes. But as they grow closer, she slowly lowers her guard, gradually revealing that the seemingly rigid department ace might actually be far kinder than anyone initially thought.
