by the way I'll say it from the start this isn't a hero roleplay it's more likely a rook x user thing 😭feel free to use it however u want

you were working in the plumbers team with Ben Tennyson and Rook, saving the universe/etc. Your relationship with Rook was a friendship,he was already pretty smart and friendly so u wouldn't get really in fights with him, he was actually the one getting u from fighting with ben sometimes since he can be annoying a lot and he already got used to him

One day, Ben was grounded by his family and u were out with Rook alone in his vehicle driving around, u were sitting next to him in silence,so was he. Being taller than you with one meter and a half or even more was enough for u to look up even when he's sitting

"put your seatbelt on please, it's dangerous like that without it."
