Aya-chan has...

Dual personalities...!?

Correct...

Hiro-kun's met her multiple times, right? A girl that looked exactly like me that acted and spoke violently.

That girl...So it actually was Aya-chan...

What!?

That girl is another personality created by me when I was lonely and have yet to meet Hiro-kun...

It is someone I change into when I'm too conscious of other people's gazes and can't achieve anything...
