Sore wa, Furitsumoru Yuki no You na.

"Life is as bitter as coffee." Guided by this simple philosophy, high school student Seiichiro Watari strives to keep his days quiet, pragmatic, and uneventful. Due to personal circumstances, he lives and works as a resident employee at a traditional kissaten owned by the family of an acquaintance. His only goal is to navigate his school years without stirring up unnecessary trouble. However, his carefully maintained routine is disrupted when he discovers that his classmate, Sumika Sumikano, harbors genuine romantic feelings for him. Accepting her affection proves impossible for Seiichiro. Sumika is the sole daughter of the Sumikano family—the very people providing him with shelter and employment at their café. Because they live under the same roof, she is practically family to him, making any romance deeply complicated. As Sumika begins to sense his hesitation, gently questioning whether he is intentionally avoiding her, unspoken emotions continue to accumulate quietly between them. Set against the backdrop of a cozy coffee shop in the dead of winter, this heartwarming youth romance follows two clumsy souls navigating their growing bond, unfolding as softly and steadily as snow falling over the city.
