I love the Matt/Shiro BrOTP so have some headcanons that have been sitting in my drafts for weeks
-Matt is a living meme and Shiro questions their friendship every day
-“You know you love me~”
-Everyone questions how someone so calm and mature can be best friends with Matt and Matt kinda laughs in their face
-Matt: Calm? Mature? This guy almost fought a five-year-old over a chocolate bar!
Shiro: I really like the brand oKAY???
-Matt has tried to set Shiro up on one too many dates. It’s really easy since everyone and their mother has a crush on Shiro but Shiro needs Matt to stop.
-He did after a while until Shiro developed a crush on Allura. Cupid Matt was back. Shiro wanted to kill himself.
-Constantly making fun of each other because they love each other
-Shiro: Matt, if you don’t stop, I will literally sit on you.
Matt: Try me.
-You wouldn’t believe how often that happens. Spoil alert: A lot.
-They’re pretty competitive when it comes to each other. Whether it comes to bets or board games. Tears are shed. Friendships are broken. It gets pretty intense.
-Matt: I got to move on and be who I am! I just don’t belong here, I hope you understand! We might find our place in this world someday. But at least for now, I gotta find my own way…
Shiro: Don’t you think you’re being a bit dramatic over a pizza slice?
-Once Shiro ate the last brownie and Matt wouldn’t talk to him for a week. The dude really loves his food.
Matt: This is homophobia at its finest. ://
-Once they had a convo on what their ship name would be if they dated, Shiro came up with Shatt, Matt disowned him
-Death jokes make up half of their friendship.
-Shiro: I’m going to propel myself off of this balcony.
-Matt: Not without me, you’re not.
