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!!
Matsuri went to a Halloween party with Asahi-sempai, and while there were a few moments where she was in a bind, she was still able to have a romantic and enjoyable experience. As winter arrives, the two of them prepare for their first Christmas date ever! Matsuri will get to have Asahi-sempai all to herself on the most wonderful day of the year!
