Long Haotian grew up in the mountains since childhood, and was forced down the mountain by the "old man" at home under the pretext of an engagement, originally only wanting to find his fiancee Su Qingxue to annul the engagement and continue his free and unfettered days. Who knew that just as he went down the mountain he would get to know Su Qingxue by chasing a car for compensation, and then find out that she was precisely his fiancee. From "annulling the engagement" to "pretending to be a fiance and close-up bodyguard", he was rolled all the way into the internal and external troubles of Longteng Group and Qin Yuan's conspiracy.
