The first time her heart fluttered was on the eve of freshman year military training.
At the corner of the stairs, that person stroked her head, just as always.
The girl knew what it meant, but she didn't dare admit it.
Later, when she thought back on that time, she realized how foolish she had been.
Hadn't she liked that person for a long time already?
P.S. 1v1 happy ending, an everyday school-life story.
Moral: Cherish everyone around you who loves you.
