When I started shipping or if I ship it: To be honest, anon, I haven't really given it much thought at a ship, but I can try.
My thoughts: Well we've got Killer with his mask and Penguin with his hat low over his face, so they have the sort of hidden face thing in common, right?
What makes me happy about them: Well Killer is kind of serious and practical, and Penguin is more easy going and silly, so I guess it would be a little cute to see them interact and watch Killer be confused by Penguin's lack of concern.
What makes me sad about them: Well the whole hidden face thing could be sad, yes? There could be something there.
Things done in art/fic that annoy me: I had to go through Pixiv and look at a whole bunch of art. I feel better educated, this ship is actually pretty cute. I didn't really find myself annoyed with anything though.
Things I look for in art/fic: More of it?
My kinks: Wait, be gentle with me, I'm still new to this.
Who i’d be comfortable them ending up with, if not each other: Killer with Kid and Penguin with...Shachi I guess?My happily ever after for them: I don't know. Can there be a happy ending.
Cuddles, they can end in cuddles.
I'm sorry anon! I tried, hopefully I did okay, but thank you!
