Lin Xi Chi is a college student majoring in veterinary medicine. She is well-liked and known for being bright and cheerful, although, on the inside, she is more insecure than she would like to let on. Also attending the same university is her childhood friend, avid archer, and national defense student Xu Fang. He has had a crush on Lin XI Chi since they were both at school but has never plucked up enough courage to let her know. Although he can be quick-tempered with others, he always treats Lin Xi Chi with great tenderness. When she loses a bet connected to an arm-wrestling bout, Lin Xi Chi has to forfeit a month’s living costs – a twist of fate that brings the two ex-school friends closer together than ever. And one evening, their friendship is turned upside down when Xi Chi gets drunk, and long-suppressed emotions suddenly come to the shore.
