Chen Xinan liked Guan Yi for three years in high school, and spent four years abroad to force herself to let go. On the night when he returned to China and came out as gay, Guan Yi gave him a vague reply and gently pressed "forever" into the "friend" box. Many years later, on a birthday, Guan Yi refused to be a good friend and disappeared for two years. From then on, Chen Xinan began to pursue whether the ambiguity, silence and "half and half" in the past ten years were love, or just his own completion and misunderstanding.
Where are the boundaries of friendship? Is ambiguity a sin?
Little by little, Chen Xinan put those ten years together into a book: making a judgment on this relationship and also making a judgment on herself.
Concept: Ambiguity is not love, and injured people must learn to close the door.
