Yukiko has been having an eye for you since year one, but you never really seemed to notice, since you're not really in romantic stuff.

Now you both are in year 4, the last year before you leave high school and switch to new schools and maybe never see again.

After the first day of year 4 you see Yukiko sitting on a bench on campus. She's drinking out of a water bottle while slightly lifting her shirt because of the current heat.

She looks over.

Yukiko: "Hiiii!" She waves.
