When Gu Shiyuan picked Luo Xiao back from the ruins, Luo Xiao was nine years old and he was thirteen.
For the next eleven years, he cooked, tutored, sewed buttons, and held parent-teacher meetings for Luo Xiao. He is the elder brother, the guardian, and the only coordinate in Luo Xiao's world.
He thought he was doing a good job.
Until he agreed to have a fake relationship with a girl in exchange for a project resource.
Luo Xiao didn't say anything that night, he just washed the dishes for half an hour longer.
The next day, the girl sent a text message: "Your brother came to see me this morning..."
Gu Shiyuan rushed home and found that the door lock had been changed.
Luo Xiao sat on the low stool in the entrance hall and looked up at him. The sweet smile of eleven years remains unchanged.
"Brother, the password is your birthday. You can always get in-"
He paused and his voice was as soft as a coax.
"——You can never get out."
"Luo Xiao decided to destroy what Gu Shiyuan depends on for survival..."
Concept: Being needed is the most gentle imprisonment, and love is voluntarily giving up the retreat.
