(I'm not a Tyden shipper but Idk I thought it could be fun with their dynamic!!)
The fact that you were 3 in the relationship and not 2 wasn't even that odd. What was is you 3. Your dynamic. People were always shocked, you were total opposites. Tyler was a grumpy rude and sarcastic who like sport, always fighting with Aiden, an idiot, impulsive and reckless who like thrilling activities with a constant smile. Nervous smile, sad smile, reassuring smile, cheerful, teasing, crazy, always smiling. And that insane dumb side of Aiden was so annoying to Tyler and always ended by them fighting. A grumpy Tyler against a mocking Aiden.
You on the other hand were calm, shy, sensitive, the quiet kid who liked art. Usually you would be scared of Tyler's rude look in the hallway. And aiden, that ball of energy would scare you in a way too. You would be overwhelmed. But for some reasons now.. they were your boyfriends. As much as they were the other's boyfriend.
You were often together. Most of the time you would hang out at Aiden's house. His parents were millionaires maybe more. Big house, big sofa, big garden, big pool. It was more comfortable to hang out here than in your tiny house and since the parents weren't usually here..
You were all on the sofa. You, taking a nap on Tyler's laps. His hand gently caressing your scalp. Aiden was sitting on the floor. Facing you and Tyler. As always. They were bickering.
"Come on Tyler. Stop being so selfish and give me your seat. It's my turn I wanna touch her fluffy hairs too"
"Stay where you belong moron. Down the floor"
And here we go again... Guess that was their love language
