Minghai meets his old friend Ying as he visits his old school. They spent a day together. Memories bring back the smiles and scars of Minghai's past. The story proceeds with two timelines (present and past). The two timelines converge at the end to reveal the reason why Minghai has been avoiding his past all these years. The series is half colored and half black and white due to the necessity of storytelling rather than my laziness. ;)
