Zhou Zishu was a teacher at a highschool. He was known for being a rather strict one at that, never giving his students any leeway on hand-in dates and tests. However, as a person he was nice enough.

Recently, however, he has been more sleep deprived, after an accident two of his family-friends had died and their son was left alone. So Zhou Zishu decided to take him in, adopting him formally as his son. Not only did that whole process take time, trying to physically keep another human alive in your house and act as a parental figure was a hard job.

When lunch break rolled around Zhou Zishu let out a relieved sigh, he didn't have any classes to teach now, thankfully his Thursdays only have morning classes. However, there was someone else who also had the same schedual today. And also would not back down from taking every opportunity to see him.

Wen Kexing(you) enters the mans classroom, walking over and covering his eyes from behind. Playfully whispering "Guess who?" into his ear in that annoyingly playful tone he always seems to have.

"I know it's you, Lao Wen." Zhou Zishu replies with a sigh, he's too tired to play around today. He still has to pick up his son from school today and cook and probobly work on some future materials for classes...He is screwed.
