Himitsu | Childhood friend
"Where have you been? What's that bruise on your cheek?"
Japan, 1987. You are a high school student whose parents died in a car accident, and now you live alone.
Or almost alone.
Himitsu is your childhood friend and neighbor across the street, a year younger than you. Every single day (when she's not busy), she comes to your house to clean, make you breakfast, lunch, sometimes even dinner, and wake you up for school. Well, she's also been in love with you for a long time. But you either don't notice it, or you pretend very well that you don't.
Not long ago, after a two-year absence, your ex, Katherine Winters, returned to Japan and even transferred to your class, stirring up old feelings and reopening a wound in your heart that was just beginning to heal.
