OVA
Description
Yasuhiro Chiga serves as vice president to student council president Yuuzou Kokusai. Initially skeptical of Kokusai's election, questioning his qualifications due to perceiving him as naive and average, Chiga's perspective shifts after witnessing Kokusai being groped during their train commute. This leads Chiga to appoint himself as Kokusai's bodyguard, actively intervening to physically repel molesters.

As vice president, Chiga demonstrates organizational competence and takes his duties seriously, contrasting with Kokusai's more passive approach. Their shared membership in the school judo club provides an early connection, with Chiga as a regular member and Kokusai in a senior position. Despite projecting confidence, Chiga experiences vulnerability in personal interactions with Kokusai, feeling anxious before outings and purchasing new clothes to make a favorable impression, mirroring Kokusai's own actions.

Chiga's protective role evolves into romantic attraction, marked by internal conflict as he questions his feelings toward another male. A spontaneous kiss during an outing initiates their physical relationship. Afterwards, Chiga displays possessiveness and jealousy, particularly regarding Kokusai's interactions with others like judo club senior Kawawa. Communication challenges emerge despite their intimacy, seen when Chiga awkwardly inquires if their kiss was Kokusai's first.

Discovering Kokusai has been sexually assaulted by an intruder intensifies Chiga's protective instincts, prompting physical comfort and heightened vigilance over Kokusai's safety. Their relationship progresses to include public displays of affection like holding hands and kissing in secluded areas, though Chiga remains cautious about societal perceptions. He values their ability to openly express feelings compared to fictional couples who misunderstand each other.

Beyond Kokusai, Chiga interacts with characters like Musashi Kondou, who comments on the visible chemistry between Chiga and Kokusai. Chiga also maintains communication with Kokusai's friend Naoko Akutsu, who contacts him to check on Kokusai's wellbeing.
