Ok so-yes, and I love those two together BUT-and hear me out here-
I almost feel like him and Shinsou would work better.
So listen, listen-I FEEL LIKE-and this is just a headcanon thing but I 100% feel like this is a thing-Shinsou would be REALLY, REALLY good at helping people through panic attacks. Because HE definitely has a lot of anxiety and depression issues and I feel like he has that thing(which is a thing I have btw-) where he's been to so many therapists at this point that he just has basically become a mini-therapist for everyone else(JESUS CHRIST I'M A SHINSOU KINNIE-) Like he's definitely just the therapist of his friend group.
BUT ALSO-
he's got the whole, "I have a villainous quirk and everyone hates me for it ;-;" thing going on but LISTEN-LISTEN YOU KNOW WHO ELSE HAS THAT!? Lukas. His is a little different because it's less "I have a villainous quirk" and more- "I have no control over my quirk and I'm TERRIFIED of it" but they definitely share the general like-somewhat dislike of their quirks.
THREE-
If you think Shinsou wouldn't just like-brainwash the shit out of every HPSC officer/pro-hero that came Lukas's way with NO collateral damage you DEAD wrong-none of them know his quirk so literally he could difuse those situations so quickly-
FOUR-
Cat boy and dog boy. :)
FIVE-
Lukas is a loud blonde.
OKAY-, we LITERALLY, NEED, shinsou to be the therapist, because look-you may think someone like, idk, MINA would be that, but no-IT'S SHINSOU, and yeah, they really do fit, they both have somewhat the same issues, (minus the depresso thing for shinsou), and well, in every way they do!......and yeah, hate for their own quirk. TvT
And trrrruuuue, like seriously, shinosu would actually be the BEST bet for disfusing things with lukas. -v-
puurfect-
and Yeah, better version of Katsuki! >:D
PFFFFFFFFFFFFFFFT-
I mean come on, I'm not saying it's something like katsuki and momo, really! I love the ship, it's just how people sometimes make it. Anddddddd well-there's not VERY many things that would lean towards deku n shoto,obviously-there are some, admittedly, very leaning towards that side scenes, but they are also then like-joke parts. XD
