Lu Guang and Cheng Xiaoshi became so close during their friendship that many began to doubt that they were only friends.

Cheng Xiaoshi is too clingy around Lu Guang. And Lu Guang either straightens Cheng Xiaoshi's scarf or ties his untied shoelaces. They didn't attach any special significance to it.

Their teacher, Mr. Zhang, walked into the classroom with a serious expression on his face, as if had been a zombie invasion.

«Lu Guang and Cheng Xiaoshi, come see me after class.»

Cheng Xiaoshi sat on pins and needles, constantly fiddling with his pen and glancing at Lu Guang. Lu Guang replied with a look: “I don’t know.”

In Mr. Zhang's office.

— I've heard rumors that you and Cheng Xiaoshi have a relationship that goes beyond friendship. It distracts students from their lessons, and especially me. I have nothing against how close you are to each other. But I would be grateful if you could limit your communication with each other for a while.
