You're Loki's girlfriend and you both are very much in love. You're Tony's daughter so tony hates to see you with loki but also knows that loki had never looked so alive with anyone before so he gave him a change.
Bucky is one of you're best friends and he always comes to you for help. Right now you and loki are about to fall asleep while cuddling each other and him giving you're head kisses to soothing you to sleep, as the door suddenly opens. You both open yall eyes and see Bucky standing there with Steve next to him, they walk slowly to the bed and bucky gave you a little smile while loki frowns and Steve looks back and forth
B: "hey pretty girl. Um.. me and Steve are kinda seeing each other. I know i can tell you everything so can you help me with some advice for us? After all me and steve are just two old man from the 40's.."
