>>2427156This is a chart-like picture that can be found for other characters as well.
Loosely translated, it would be "20 Smiling looks" or "glances" as the character is looking at you. There are 19 standard titles with 1 optional at the lower right for the artist to originate.
You can google image "笑顔だけで表情20" to see more characters with the 19 standard boxes.
First row: "Usual" "praised" "refreshing" "shy smile" "expecting"
I'll leave the rest for someone else.
