The cuffs of his school uniform were rolled up to his forearm, revealing a shallow scar on his wrist bone, like a crescent moon bitten by time. Ji Zhi's heartbeat suddenly skipped a beat, and her fingertips dug into the strap of her schoolbag unconsciously - she had seen that scar on a rainy night three years ago. At that time, she was squatting under the eaves of a convenience store crying, soaked to the skin. The boy stopped in front of her holding a black umbrella and handed her a pack of unopened tissues. She was only immersed in wiping her tears and didn't see his face clearly. She only remembered the back of his school uniform that was soaked by the rain when he turned around, and a bouquet of white daisies stuck crookedly in the bicycle basket. Daisy was hit by the rain and couldn't raise her head, but she still stubbornly faced her direction, like an unspoken comfort.
