You had been in an abusive relationship for the past 9 years and on one eventful day, when you partner was just about to bang you head against the wall, for disobeying them and forgetting to make their favourite food for dinner, the door of your apartment burst open, standing in all his glory was Tony Stark, aka iron man.
Flashback
"Hurt the lady once more and I won't hesitate to blast your peanut sized brains" He said eerily calmly.

Behind him stood a green hulk,  back widow, Hawkeye , Thor and captain America

"Hulk smash, hulk no like abuser" With that he took a step closer to your partner who still had a death grip on your hair.

Tony came forward and removed their fingers while hulk picked them up and heated them out the tower.

"We will take care of them, Tony you check on her" Said Steve as he and the other four followed hulk to take care of your ex partner.

"Sweetheart, are you alright? " Asked Tony as he crouched down in front of you

You shook your head and started crying

"Oh, honey, don't sorry that shit head can't hurt you anymore, the entire shield will destroy them" He said as he gathered you in his arms

"How did you guys know I needed help" You asked

"We were battling a few aliens and I had just fallen down from a hole in the sky and woken up, we were about to go to have some Shwarama when we heard you scream, thinking an alien or two were left from being killed we came running here only to find a worsor problem and hence we are here. Now you will stay with us for a while till we can get you back on your feet"he said and you nodded, thanking him over and over again for his help.
Flashback ends

Now you were dating the billionaire and were a well known shield agent who had kicked many asses including Loki's. Hell you even learned mechanics while helping him in the lab. You and Tony jad been dating for two years noe

"Sweetie pie, look what I got you " Said you boyfriend as he walked in through the bedroom door.
He held up you got making you go red

"A lingerie set, " You whispered and he nodded

"Let's spice up our bedroom life and also show off you beautiful curves" He said

Let's say the night was a long night. Tony never fails to show you how beautiful and strong you are . He never fails to remind you that that scumhead never really deserved you. In return you showered Tony with all the love you had to offer and appreciate him every single day, for rescuing you that day.
