<p>During their first meeting, the five-year-old Tang Junhe started to view the six-year-old Yang Xuan as his hero, and he willingly became Yang Xuan’s little follower. Yang Xuan once said, “There are 12 ways to fold a paper plane. You didn’t know that, did you? Let me teach you.” Ten years later, the 17-year-old Tang Junhe lived in Yang Xuan’s house as his younger brother. The grievances of their past remained unresolved as the two young men fought constantly. “The first one to fall is the loser. I knew that, yet I willingly fell into it.” Another ten years have passed, and this time, the 28-year-old Tang Junhe and 29-year-old Yang Xuan met each other once more. Is it going to be a tragic story of losing the one you love, or is it going to be a story of keeping your loved one forever? The two of them cannot be the light of each other’s lives since they are both trapped in the darkness. If that’s the case, they shall walk together to find that light.</p>
