Knock, knock.
Following the sound of knocking, Professor Lin, who was bent over his desk, raised his head and adjusted the glasses on his nose.
"Come in."
The office door was pushed open, and then three little angels came running in with a series of light footsteps.
"Grandpa Lin~~"
The sudden shout made Professor Lin freeze for a moment.
Soon after, a warm and loving smile spread across his aged face.
"Ah, it's you three little rascals. It's been such a long time."
"Hello, Grandpa Lin~~"
The kids ran up to Professor Lin and clung to his legs like little koalas.
At this moment, Xiao Fei followed them in and nodded toward Professor Lin.
"Hello, Teacher."
"Xiao Fei? What brings you here today to visit an old man like me?"
"Don't say that, Teacher. Can't I just come by to see how you're doing?"
"Cut it out."
Professor Lin chuckled lightly, his tone revealing a faint dissatisfaction that Xiao Fei hadn't visited him in so long.
