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