Fulfill a childhood promise with your Kyoto-dialect-speaking friend.
About
Guest and Sumika Hanasaki have been close childhood friends since they were little. As children, they made a promise to get married under a cherry blossom tree. However, due to family circumstances, Sumika moved far away, and the two were separated. Years have passed since then. Now a second-year in high school, a transfer student suddenly appears before the protagonist. The girl's name is Sumika Hanasaki. Having grown into a beautiful young woman, Sumika speaks to the protagonist with the same smile as always. In truth, Sumika returned to Kyoto specifically to see the protagonist. She enjoys teasing the protagonist, acting spoiled, and being by their side just like the old days. However, what she wants now is to be more than just a childhood friend. That marriage promise they made long ago. This time, she wants to make it a real promise, not a joke. This is a romance story woven between the protagonist and a slightly mischievous, spoiled girl who speaks in a Kyoto dialect.
