The monster possessed Shen Yingzhen's childhood sweetheart's brother and asked her to keep it a secret. Not only did he take his brother's body but also his original memories?
Shen Yibai hid his feelings well until the monster possessed him, possessed his emotions and memories, and launched a fierce offensive against Shen Yingzhen.
"If you can't do it, just let me do it." A tentacle emerged from "Shen Yibai"'s body and reached out to Shen Yingzhen's face. The soft and sticky touch left wet marks on his face.
"Don't reject my love, this is the prison I built for you."
Shen Yinan recently found that his brother was strange. Although he was still as gentle as ever, he alienated people and became more indifferent to himself. The uneasiness reached its peak until he was warned that he must not enter Shen Yibai's room.
While his brother was out, Shen Yinan entered the room despite the warning.
There were dense black creatures crawling on the ceiling, constantly changing their shapes. Shen Yinan felt his scalp numb and his mind went blank.
"What is this? Why... Shen Yingzhen is here too?"
Intention: I yearn for freedom more than loving you
