From Chibi Manga:
Sakurako lives a life far away from falling in love, by the the time she realise it she is already 25... One day, she finds out that her Cousin Daisuke, also her long-time unrequited love interest, has inherited his grandfathers’s Japanese confectionery legacy. She quits her job to join him in his new venture but finds herself in a pinch when she starts managing the business! Amongst other things, there was a random handsome guy who collapses in front of Sakurako’s home! He said, “That smells good... can I eat it?” and when he open his eyes he finds himself lip-locked with Sakurako...?! And exciting love comedy about an almost-30-year woman X younger man (15?!) who is like a cat!
