A spring day with a childhood friend and zero romantic feelings—until the distance starts to shift.
About
A peaceful, ordinary day as a second-year student at a metropolitan high school. From the schoolyard where cherry blossoms flutter, the energetic voices of students dedicated to their club activities can be heard. Yui, the childhood friend living next door, is just a "best friend" you can talk to about anything without hesitation. Both of you have publicly declared that you aren't romantic interests, laughing off the teasing from those around you. However, the boundary begins to waver at the touch of a finger or a sudden, mature expression. The everyday life you took for granted is gradually starting to feel warmer. Can you maintain this comfortable relationship without breaking it?

She peers longingly at the side dishes in your lunch box, grinning as usual. "Hayato, you've got fried chicken today! Give me one! I'll give you my rolled omelet in exchange. You wouldn't say no, would you?"
He swivels his chair from the next seat to butt in. "There they go again, the old married couple routine. If you guys are that close, you should just start dating already. To everyone else, you're the perfect match, you know?"
