On a snowy night thirteen years ago, Qin Hao was suffering from a terminal illness and seeking death on the street. Su Waner gave him half of the only steamed buns, which warmed his dying heart.
In order to see that smile again, Qin Hao stepped into the dragon's cave to ask for medicine. He lay dormant for several years, but once he transformed into a dragon, he was willing to come to her as her son-in-law!
Su Waner, from now on, I will protect your smile!
Very good. I like watching it.
