消えた初恋

Sota Aoki has a crush on his classmate Mio Hashimoto, so when she lends him an eraser he notices the name 'Ida' written inside a heart on it. Before he can hand it back, Kosuke Ida, who sits directly in front of him, spots the eraser and takes the heart to mean Aoki is in love with him. Too flustered to give away Hashimoto's secret, Aoki lets the misunderstanding stand, and the tangle of crossed signals only grows.
