Delulu not solulu

Zhai Tianyu placed Su Tai on the pillow before turning on his heels and stepping out of the room where Su Tai was entertaining him. For the sake of pretending that he was going to sleep, he faked a yawn with his hand in front of his mouth. 

He then opened his room's door and went inside. Zhai Tianyu knew that the shadow guards must be paying attention to his room to make sure whether or not he was sleeping. After all, Su Tai was the kind of man who was only gentle and hard-working on papers, if the truth were to come out then that man would be the one who would suffer the most! 

He closed his eyes and silently counted the number of shadow guards that were neatly arranged next to his room.
