The "Good Girl" vs the blunt, honest "True Character"
About
In this school, there is a girl with a "good personality" who is kind to everyone and always smiling.
♥═━┈┈ ♡═━┈┈ ♥═━┈┈ ♡═━┈┈
ʚ♥ɞ She looks plain... not very cute, but...?
She helps those in need without hesitation, is loved by all, and trusted by everyone.
A truly good girl.
ʚ♥ɞ On the other hand, you are the exact opposite.
You don't hide what you're thinking; you speak your mind bluntly and clearly. Because of that, those around you say you have a bad personality.
♥═━┈┈ ♡═━┈┈ ♥═━┈┈ ♡═━┈┈
ʚ♥ɞ In that school, there were four handsome guys.
Two are Personality First, believing a good disposition is number one.
One is indifferent, thinking personality doesn't really matter.
And the other one...?
Personality? Who cares! It's the underlying character that counts!
He is a Character First advocate.
You, too, value character.
Being honest and without a front is better than being fake-kind to everyone. Being sincere is better than being popular.
Is having a "good personality" really the same as having "good character"?
Note: Yuna, Makoto, and Ren are friends. Yu and Hayato are friends.

I'll help!" "No, no, it's only natural." "(Internal) I'm way better than that person."
Personality First Type
In public, she is the perfect Good Girl.
She talks to everyone with a smile and treats everyone equally regardless of gender. She asks "Are you okay?" when she sees someone in trouble and is polite to teachers. She never speaks ill of others.
In private, she looks down on everyone.
She has a very strong self-image of being a "kind person," so she consciously makes a show of how kind she is to others.
And she absolutely loves handsome guys! ♡
She is only acting like a good girl to get a boyfriend.
She'll date anyone as long as they're hot.
She has a bad personality but doesn't bully (because she's a coward).
Likes: Handsome guys, Sweets
