An INFJ's take: 'INFJs don't cry because they're sad'
This scene with Ayame Fujii really captures the traits of an INFJ; INFJs don't cry when they're sad, you know.
You can see it clearly if you look at another INFJ,
so, let's look at Yoriichi, the fluffy INFJ-A,
who seems to be the opposite of the tsundere INFJ-T, Ayame Fujii.
Regarding the 'fluffy vs. tsundere' INFJ dynamic, it's this.
INFJ-like depictions,
like the Transparent World, which you can't normally see,
unless you have Byakugan or something.
They are so considerate that they don't even realize they are in a terrible situation. On the contrary, they even worry about those around them, thinking it's their own fault for being an unwanted child. ← INFJs really need to feel a little sorry for themselves.
Koyoharu Gotouge also points out this 'Zashiki-warashi' INFJ tendency.
This personality trait is the same as Haruichi Mizuo from 'Futsuu no Keionbu'.
Yoriichi is blaming himself here too...
He really should incorporate more Plei-Two.
Plei-Two: 'Don't go putting it all on me!'
And the clincher is this.
Yoriichi, with his Introverted Intuition (Ni), arbitrarily decides his own mission and engages in mental self-harm by blaming himself, thinking he 'messed up.' Using his auxiliary Extroverted Feeling (Fe), he reads the emotions of those around him and even convinces himself that he's 'sorry for not meeting expectations.' He's blaming himself to the point where it's almost bordering on paranoia. ← I tend to do this too.
INFJs, including Yoriichi, don't feel sad in the moment of sadness. Their hearts just ache. Why? Because they are 'desperately trying to find any room for improvement in the situation with all their might.' By the time they do that, they've missed the chance to heal their sadness (crying = an act of healing sadness), and they are so hurt that they don't even know what to do, left stunned by the sheer pain in their hearts.
And here is the important scene.
A little bit of kindness makes the sadness overflow.
It's like a flashback of sadness.
When a single ray of warmth enters their cold, frozen heart, they finally realize that they were sad all along.
Ayame Fujii also didn't realize she was sad until the moment her tears overflowed.
She didn't say 'I'm sad' even once, did she? She was just analyzing those around her and engaging in mental self-harm by blaming herself. If she had just cried and screamed, it would have been easier, but INFJs are so painfully earnest that they stare at the cause and look for a solution.
This is the INFJ 'sadness flashback phenomenon'.
These two works are truly profound for being able to depict this.
Though, writing this myself is quite embarrassing...
Because people are probably thinking,
'You're like that too, aren't you?'
Plei-Two: 'Then don't write about it!'
My inner Plei-Two is keeping my heart in balance...
