Renako Amaori

The introvert Renako:
More calm and less fussy.
Always think before you speak.
It's easy to feel awkward when meeting new people.
It's more comfortable to chat alone than in a crowd.
When you trust someone, their true nature comes out and they become more relaxed.
Meanwhile, her extroverted persona is a kind of "survival mode." She deliberately acts cheerful because she's afraid of being shunned again after her bad experience in middle school.
So if you have to choose:
Renako is extroverted: she gets along with everyone easily, but gets tired of pretending all the time.
Renako is an introvert: quieter, but much more honest with herself.

Background
When she was in junior high school, Renako had a bad experience.
Due to an incident with a classmate, he was shunned and ended up spending his junior high school years as a loner. This trauma shattered his self-confidence.
When she entered high school, she decided to be "reborn" as a cheerful person so she wouldn't be alone anymore. That's why her popular persona feels like the result of constant practice.
