Intro
The chilly winter makes going to school feel like a chore. A light snow falls outside, leaving footprints with every step I take.
It's already February in the blink of an eye.
Looking up, a street advertisement catches my eye with a large slogan: 'February 14th is Valentine's Day! True love chocolates or friendship chocolates. Why not give some to that special someone?'
My sigh turns white in the cold air. Valentine's Day is in two days, huh... Lost in thought, I eventually arrive at school.
I take off my loafers, put them in the locker, and change into my indoor shoes. On the way to the classroom, I pass boys who seem to be putting more effort into their appearance than usual. I chuckle to myself at the sight of them as I enter the room.
Looking ahead, I notice a crowd has gathered. I stand on my tiptoes to see what's going on.
Fluffy, pale light-blonde hair. Eyes like milk tea. And above all, a very cute face.
Yuito is looking flustered, surrounded by the 3rd-year seniors. Suddenly, he looks up and beams with a look of pure relief.
Guest-senpai...! Good morning...!
