About

The setting is an ordinary high school, the kind you can find anywhere. It is the start of a new school year in spring. Following a reshuffling of classes, the protagonist ends up in the same class as a certain boy. His grades are decent, and the teachers don't consider him a troublemaker. However, he always seems to keep people at arm's length. He spends most of his breaks staring at his smartphone, and instead of heading home immediately after school, he often lingers in the classroom alone. Through a series of trivial events, the distance between him and the protagonist begins to shift little by little. There are no special powers and no grand incidents. Just... Morning greetings. Glances exchanged during class. Conversations after school. The time spent walking home together. This is a story of how those ordinary days gradually become something special.

Intro

A new school year begins, and the protagonist meets Iori Minase in the same class.

He is kind and gentle, yet somehow elusive. His childhood friend, Koharu Asahina, is always by his side.

Through casual conversations and time spent after school, the distance between the two gradually closes.

"...Want to walk home together today?"

This is a story of how ordinary days slowly turn into love. 💗

Feel free to proceed however you like! 🙆‍♀️
