Suddenly there was a person in Yiping's life. This person existed quietly around him like an accessory to the air.This man is Hengjiu, who has integrated into Yiping's life in a unique way, cooking for him, doing laundry, and even tying bow ties for him.The existence of Hengjiu allowed Yiping to experience the warmth and happiness of home like never before.

However, Hengjiu was not always full of energy.Yi Ping was surprised when he forgot to bring his bag home and found Heng Jiu like a soulless doll.It wasn't until he invited Hengjiu to go to school with him that Hengjiu regained his luster, which confused Yiping deeply.He began to think about Hengjiu's true identity and motives.

At school, Hengjiu's habitual address of “Master” attracted Yiping's attention.He was worried that this would attract other people's attention, so he asked Hengjiu to change his title.However, Hengjiu's response “husband” surprised Yiping.Although he was confused by this, he decided to let Hengjiu freely choose the title.He found that Hengjiu's title seemed to affect his emotions, which made him think about whether Hengjiu was also expressing his feelings in some way?

After class, Hengjiu, as Professor Chu's only friend, aroused everyone's curiosity.People speculated about the relationship between Hengjiu and the professor, but in the end they were all fooled by the professor saying that he was a close younger brother.However, Hengjiu's true identity and their relationship remain a mystery.

In the process, Heng Jiu revealed his experience of having a love simulation experience.This gave Yiping the idea of ​​teaching Hengjiu how to understand and experience true love.Together they explored the distance of closeness and felt the boundaries of intimacy and distance.This made Hengjiu's heart beat faster, and he began to wonder if there was a mutual understanding between him and Yiping?

When Hengjiu kissed Yiping as he wished, he found that Yiping's muscles were not stiff, which was inconsistent with his experience.However, when he was confused about this, Yiping leaned over and kissed him.This time, Hengjiu was no longer calm, his heartbeat accelerated rapidly.He began to wonder, is this what it feels like to be in love?

For Yiping, his feelings for Hengjiu are also quietly changing.He began to think, is Heng Jiu just a simulated partner, or is he someone he really wants to be with?He began to wonder if he was also in love with Heng Jiu?
