Tomoya Asahina acts as manager of Café Noël, stepping into this role after the original owner was injured saving his life. He oversees the café throughout the owner's recovery. Possessing a handsome appearance marked by gray hair and ochre eyes, Tomoya combines kindness with a strong sense of duty. Despite his attractive qualities, he remains reserved around women due to limited romantic experience, often causing hesitation and uncertainty when initiating interactions. His sincere efforts focus on revitalizing the struggling café.

To attract customers and restore the business, Tomoya implements a significant strategy: transforming the café into a cosplay-themed establishment where the waitresses—all married women—serve in revealing costumes, leveraging their appeal to draw patrons.

In his personal life, Tomoya navigates complex relationships with the staff. Waitresses Kanae Mashita, Ryouka Fuwa, and Seia Sakaki pursue him actively, driven by dissatisfaction in their marriages. However, his romantic interest centers on Akiho Onose, a widow among the staff. His feelings for her develop rapidly, though she initially keeps her distance. Demonstrating his supportive nature, Tomoya consistently assists Akiho with her daily tasks, prioritizing her well-being over any reciprocation of his feelings.

Spanning two episodes, the narrative follows Tomoya managing the café and interacting with the waitresses, particularly their attempts to educate him about romantic relationships. His core traits—sincerity, romantic inexperience, and dedication to both the café and Akiho—remain central throughout these events.
