High schooler Matsuri has an unexpected encounter with her brother’s friend, Asahi-sempai, who also happens to be a popular boy at her school. From then on, Asahi-sempai makes passes at her at school or even at her own house! Wherever Matsuri might be, there’s just no escaping him… Every day with the somewhat perverse Asahi-sempai is an unbelievably stimulating experience for Matsuri, and she can’t help but be flustered!!
Summer vacation has ended, and romance is in the air! Matsuri feels that she has gotten much closer to Asahi-sempai. One day, she asked him why he doesn't want a girlfriend. The answer she got was not something she could have expected ... In order to learn more about his feelings, she asked him to go with her to the Labyrinth of Love (a place only couples can enter)!! She then got to spend one day as a couple with Asahi-sempai during the school festival!
