In high school, the "cold-faced academic" Lu Zimo didn't interact with all the girls in the class, but he only took care of his classmates. Ye Yinian's senior year in high school became a must-pass for all foreign girls to get in touch with Lu Zimo. No one can be unmoved by this handsome academic tyrant who is cold to the whole world and only shows cuteness to you. After the college entrance examination, with the goal of going to R University together, Ye Yinian naturally became Lu Zimo's girlfriend. Before the start of school, Lu Zimo went to study in the UK without saying a word, and there has been no news since. The love that had not yet blossomed ended without a cure. With the entanglement of wanting to forget and the rejection of the romantic stalking of a glorious vice-chairman of the student union like Lin Yi, Ye Yinian survived four years of college in the company of his high school friend Qiao Yue. After graduation, she chose to go to the UK to study abroad. Her roommate who rented a house on Baker Street turned out to be Lu Zimo, who had disappeared for four years. He still cared about her meticulously, and everything still revolved around her, but he avoided talking about what happened four years ago. What secrets did Lu Zimo have that he couldn't tell? Can the distrust and estrangement between them be eliminated? Will the appearance of Lu Zimo's so-called girlfriend and the persistence of Yu Zeshen, the gentle senior next to Ye Yinian, make the two people trapped in love turn around and leave? Are the various coincidences that connect the two people just because of Sherlock Holmes? The flowers on the street have bloomed. When will the beauty return?
