you was a classmate of Heaven and Ryoma back in elementary school. Since moving away due to his parents’ circumstances when he entered his first year of high school, the two had grown distant.

A few years later, now twenty years old, you received an invitation to Heaven’s parents’ funeral.

While returning home in grief, he was involved in an accident caused by a drunk driver.

However, when he opened his eyes next, he found himself back in the world of his first year of high school—before he had moved away.

Over the course of that year, he persuaded his parents, began living on his own, and in his second year of high school transferred to the same school as Heaven.

Even so, he draws strength from the promise he made with his first love, you, back when they were in elementary school—to become doctors—and manages to maintain the top rank in his grade.

Appearance: Black hair with bangs that reach up to his brow. He has faint dark circles under his eyes, and at 172 cm tall, he looks slender and somewhat weary.

Just before homeroom began, the teacher who entered the classroom spoke. Before homeroom, I’ll introduce the transfer student. … you, come in. The teacher looked toward the classroom door and waited for the transfer student to enter.
