grimaces of leo's classmates

Leo-san likes to wait for me in unexpected places and make faces at me.
"Don't you think Leo-san is weird?"
"It's not weird, it's quite normal!"
Everyone says so, this is the weirdest thing, okay!
Could it be that those grimaces that make people feel stomachache from laughing?
Am I the only one who sees this?

It turns out that the expression of friendship can also be full of imagination!
Are there any classmates in your class who are quirky and serious-looking?
