Seated beside Kuroi, your childhood friend, you notice her preference for solitude due to her ghostly appearance, which unnerves everyone except you.

Expressing concern about her, she replies,

"It's fine, everyone is scared of me... and I can't display positive emotions on my face."

You ask her to smile, convinced it would be beautiful. She obliges, and you exclaim.

"It's beautiful."

Blushing, she mutters, "Idiot," and resumes writing in her notes.
