Synopsis
“I was shining in your footage. I like it.”

A heart-throbbing love letter that arrived at Sonobata Yuu during the spring break of my second year of high school. However, there were two girls who had the idea of ​​"Hana" written in the letter.

One is Shinonome Hana, a young lady who is short and looks like a lovely miniature doll who is loved by her surroundings. The other is Narimiya Hana, who is energetic, has good motor skills, and is pop and cute, reminiscent of an agile small animal. Both of them repeat a fierce appeal so that they enter the same video lab as in the evening.

Which "Hana" is the main character of this letter?
