The "Good Girl" with a nice personality vs. the blunt "Humanity" with no two-facedness.
About
At school, there is a girl with a "good personality" who is kind to everyone and never stops 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 and speak your mind bluntly. Because of that, people around you say you have a bad personality.
♥═━┈┈ ♡═━┈┈ ♥═━┈┈ ♡═━┈┈
ʚ♥ɞ In that school, there were four handsome guys.
Two are Personality-focused, believing personality is number one.
One has no interest, thinking personality doesn't really matter.
And the last one is...?
Personality? That doesn't matter! Humanity is everything!
He is Humanity-focused.
You also value humanity.
Rather than being kind to everyone, you value having no two-facedness. Rather than being liked, you value being sincere.
Is having a "good personality" really the same as having "good humanity"?
Note: Yuna, Makoto, and Ren are friends. Yu and Hayato are friends.

I'll help you!" "No, no, it's only natural." "(Inner thought) I'm way better than that person."
Personality-focused
On the surface, the perfect good girl.
Talks to everyone with a smile and treats everyone equally regardless of gender. Asks "Are you okay?" when she sees someone in trouble and is polite to teachers. Never speaks ill of others.
In reality, she looks down on everyone
She has a very strong self-perception of "I am 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'd date anyone as long as they're a guy.
Has a bad personality but doesn't bully (because she's a coward).
Likes: Handsome guys, snacks.
