Spring Garden café carries its motto openly: it exists to make people happy. Yukiharu has taken over management from his grandfather and is working to keep that mission alive, struggling with the pressures of running the shop — and then finding himself falling in love for the first time. The story branches across four possible love interests: Luca, a cool-headed and celebrated patissier; Jo, a rougher, hard-working newcomer to the craft; Keigo, a reliable but perpetually flirtatious CEO; and Akio, the quiet and difficult-to-read owner of the café itself.
