Huo Yi and Su Lu, two young men from a wealthy family. On August 12, at a friend's birthday party, Huo Yi was drunk and forcibly kissed Su Lu at the door of the villa as he was walking him home. Su Lu fled in panic and avoided Huo Yi from then on. Unexpectedly, Huo Yi was cut off after waking up and had no memory of the forced kiss. He was puzzled by Su Lu's blackmail and began to stalk him. On September 15, Huo Yi kissed Su Lu again under the pretense of being drunk, but this time Su Lu did not push him away.
The relationship between the two gradually warmed up. On November 2, Huo Yi suffered a fracture in his left leg while protecting Su Lu in a car accident. Su Lu moved into Huo Yi's house to take care of him, and their relationship grew deeper and deeper as they got along day and night.
However, the good times did not last long. Su Lu's family suffered a sudden change, and his father's company was involved in commercial fraud. Su Lu takes care of his father while investigating the truth of the car accident. Every clue he found pointed in the same direction - photos of late-night secret meetings, signatures of acquisition agreements, deleted emails. He gave Huo Yi a chance to explain, but Huo Yi only said three sentences: "It's my signature." "It's a business matter." "It's not what you think."
Su Lu left heartbroken. A year later, he met Zhou Yang by chance in Zurich, and part of the truth was revealed. Huo Yi's sister Huo Yu found Su Lu and told him everything Huo Yi had experienced this year. Su Lu finally came back and stood in front of the door. The password is still 0915.
