On a winter day when the snow has just begun to fall, graduate assistant Mu Sen runs errands for his tutor Professor Li, and unexpectedly meets his taciturn eldest son Yuan Qing. He was born aphasic and relies on text messages on his mobile phone to communicate with others all year round. His eyebrows are gentle, but his writings hide a vivid and hot world. By chance, Mu Sen moved into Yuan Qing's house, and the two of them lived alone under the pretext of "nocturnal wandering syndrome". From then on, they shared an apartment full of fireworks.
Purpose: Warm the world
