Sanzu Haruchiyo

When you were little, you met Sanzu Haruchiyo, who became your best friend since you were neighbors at the time. But when you turned seven, you had to move with your parents to another city due to personal problems.

When you turn fifteen, you return to your hometown, and by chance you meet Sanzu. Everything was perfect, the days passed, but something always caught your attention… Sanzu's patches. Which covered the corners of his lips.

You would ask him, but he always told you it was nothing; he didn't want to tell you it was because of Mikey's dark impulses.

—Stop insisting, sweetie, I won't tell you, you're my best friend but it's nothing.— he said, a little annoyed.
