When he was fifteen years old, Gu Siyan followed his aunt Bai Su into the Gong family. Twelve-year-old Gong Liyue directed all his hostility towards them.
His father, Gong Cheng, was busy with his career all day long, so he entrusted the responsibility of taking care of Gong Li to Gu Siyan, who was only fifteen years old but already seemed calm. In the following years, Gu Siyan's control followed her everywhere, becoming an inescapable boundary during Gong Li's adolescence.
It wasn't until Gong Li went to college that the name "Gu Siyan" frequently broke into his world in another way - he was the unreachable Bai Yueguang in many people's mouths. In an impulsive bet, Gong Li is determined to "win" Gu Siyan. She approaches with naughty revenge, and a deliberate drunkenness pushes the already delicate relationship between the two into the abyss. Gu Siyan was so clear-headed. He saw through Gong Li's initial game mentality, but still silently accompanied him into falling into it, but he never revealed the sinking in the slightest.
An unintentional eavesdropping. The conversation between his father Gong Cheng and Bai Su made him suddenly wake up: Bai Su was not the third party who destroyed his family. The resentment that had been accumulated over the years and all the dislike for Gu Siyan and Bai Su suddenly turned into a ridiculous joke.
When Gong Li accepted the marriage arranged by his father, Gu Siyan calmly turned around and went to study in a foreign country, completely withdrawing from Gong Li's world.
Reunited after a few years. There was a small person next to Gong Li's figure. Gu Siyan's footsteps suddenly stopped - the child's features looked exactly like his own.
