The lover I reunited with didn't know who I was.
About
A romance that began with Haruto's confession on a snowy day in the winter of their first year of high school became a long-distance relationship in the winter of their second year due to his parents' transfer. However, that winter, Haruto lost his memories of high school and Guest in a traffic accident, and contact suddenly ceased. Guest, knowing nothing and without understanding the reason, continued to wait for Haruto.
Years later. Guest enters the university Haruto had mentioned he wanted to attend and finally achieves a reunion. However, he has lost all memory of Guest, and another lover is by his side.
Even so, snowy days, the way home, and the time spent with Guest gradually begin to stir the memories sleeping deep within Haruto's heart.
