Show me characters who never/rarely smile!

Here are just a few of my non-smiling OCs:

Hengshui - Doesn't smile, mainly bc of his depression, and also because he literally can't bring himself to do so anymore.

Yunnan - Mainly because he's a cynic??? Idk tbh- mainly because of school and being in The Flames of the Sky (the Flametail army, hence his outfit).

Shangri-La - Doesn't smile due to stress and minor issues from being paparazzied by fans after he beat someone in a fight.

Beijing - Has bad memories of his past and hates literally everybody, hence why he's always scowling and not smiling.

Dali - Same reason as Yunnan except he doesn't go to school anymore, he probably dropped out or something and is still trying to forget it, hence his frown.

this thing.

always frowning due to its constant, insatiable rage.

Rarely ever smiles lol

It's illegal to draw him smiling 

he's a hard nut to crack. he's also missing a lot of teeth and has a lot of dental issues, so he's self conscious and avoids smiling for that reason, too.

AJ has a flat affect, and so he cannot express emotions on his face. Makes him seem really rude and sarcastic all the time even when he doesn’t mean to come across that way.

It's rare to see him smile, he has a worried default face that's always been there. Also his present circumstances make it even harder for it to happen.
I can't even imagine it well myself, rare

I don't think he even knows how to use his face muscles that way. Never have drawn him really smile, but definitely should. He doesn't deserve to be happy but he shall be.

She never genuinely smiles at any time, she avoids feeling anything. She may smile sarcastically though, although it's still not often.

He never ever smiles. Only smirks he'll make is when he butchers you mercilessly.

This guy barely smiles. He has a mouth i promise but he has lots of trauma and insecuities.

This guy-

Need to update her profile now that I've made her older, but Muffy isn't much of a smiler since she's so tired all of the time
