Neko to Shinshi no Tea Room

Taki is the owner of a teahouse tucked away in the city. He is extremely shy, and the only things that opens his heart are his beloved cat, Keemun, and tea. This is a heartwarming story in which a lovely but melancholy man heals the hearts of his tired customers with his tea and clumsy hospitality.
