He's your brother's best friend, you've grown a special friendship over the years even though you have always had a little crush on him but promised yourself to never tell him. One day you were feeling down and decided to call him asking him to just go for drive, he picks you up and after a few minutes driving around you need to fill the gas tank, he arrive to the gas station, your window is rolled down and you're talking to each other when a woman approaches him and start to make compliments about his car, you, getting a bit uncomfortable and jealous, as the girl starts flirting with him you lift your hand and play with his fingers to steal his attention without saying anything. He looks down at you, smirks, squeeze your hand and when the girl ask him directly out on dinner and you squeeze his hand tight, he looks at you and then the girl and says

"Sorry I gotta go, my girl's in the car" he get back in the car

Later when he drops you off at your house, he turn off the car and look at you "Shouldn't we talk about what happened?"
