Li Yu met Gu Xiyun, who had a crush on him in high school, in the hospital. She used to be just a scumbag, but now she is shining and confident. In the following days, Gu Xiyun continued to receive invitations from an anti-narcotics policeman named Li Yu, who wanted him to work as a doctor in the army. Xiyun always refused, but could not resist his inner thoughts. He went to the anti-narcotics team and opened a clinic next door. It was called dedication to the country. In fact, he was afraid that Li Yu would be injured and other doctors would be too harsh and hurt him. From the indifference at the beginning, to living next door and silently paying attention, to finally going on a mission together. During a mission, let them express their feelings to each other. But the good times didn't last long. When Li Yu was pointed at by a gangster with a gun, Xiyun rushed forward without hesitation and took the cold bullet for Li Yu, but only this time: "I can only save you once, live well. I can't save others, so you can take my place and there will be more people, okay?" "Well, Yunyun, this is the first time I call you, but please don't leave." "Sorry, I have to leave. I like you to call me Yunyun, so please call me more." "Yunyun." "Listen, someone is coming. We are going to be saved." "How can you leave me first?" "Li Yu, I like you, can you be my boyfriend?" "I'm sorry, no." "Ah, you are such a person, it's not easy for people to like you." Hum . So, I may never have the chance to tell you that I liked you back then. +_+May the wind take away my voice so that you can hear my unique love for you.
