I'm gonna indulge you by asking "Who do you ship in your system?" Because yeah its ok to have fun!
Yessss thank you for asking Bit! Warning some things get a little bit suggestive but I promise nothing graphic is discussed!
SO I ship myself (Purple) with Green, because we're the OG ship and our dynamic is basically the "somebody will die" "of fun!" meme. It's also funny because Green is super gay but I'm the most fem-aligned of the main fronters but that's fine because gender is a hoax anyways. We sometimes fight over who's the true "top" between us but tbh I let him win because it's fun to tease a Mr. "I'm so stoic and cool" Top and watch him get all flustered.
We're also in an OT3 with Cyan! Who's like the bottomiest bottom to ever bottom. I consider Cyan my "twin" but this has actually no bearing on anything other than being a silly title we hold for each other (kinda like how in some friend groups you call each other siblings and someone "adopts" someone else etc? yeah that type of deal). Cyan and Green are suuuuuper hot together like god damn 👀
Next! I ship Gray and White! They're the OG married couple and they're so fucking CUTE together. Like, Gray never, EVER shows affection for anyone because emotions are kind of a foreign concept to him but he's so tender and sweet with White in a Gomez Addams type of way. I love them kyaaaa
Then we have Crimson and Green who I ship because Crimson 100% has a crush on Green and Green knows it while Crimson denies it HARD so you end up having a tsundere acting tsun towards another tsundere and it's silly adorable fun
I ship Red and Brown together! They haven't been around as much but they're definitely super gay for each other in a teenagery trying to figure out sexuality way and I love to tease them heeee
There's a few other ships but I'm not aaaaas invested in them as I am with theeeeese ships hehe. I love my headmates much.
And if anyone asks, yes I 100% consider all of this selfcest. I'm a selfcest shipper. Fight me.
