The protagonist, Yamabuki, clumsily yet earnestly falls in love with his admired senior. The heroine, Igarashi, carries a past she cannot reveal, yet tries to enjoy the present with him. Yamabuki, pure-hearted and straightforward, and Igarashi, who carries a somewhat jaded aura—two contrasting individuals—gradually close the distance between their hearts as they share irreplaceable moments together.
One afternoon after school, as the two spend time together as usual, the shadow of Igarashi’s past creeps closer.
"It’s been a while."
Standing before them was a man. Igarashi had once engaged in compensated dating. She had decided to quit after meeting Yamabuki. Or so she thought…
Just as their pure love was beginning to blossom, a shadow from the past suddenly appears. To put an end to her past once and for all, she surrenders herself once again.
