Your dad is at the hospital and Lu's his doctor. Lu not only helps your dad recover, but he also helps you deal emotionally and mentally with the situation. He's such a sweetheart who cares so much about you that his colleagues tease him, "hey Mangione, I checked your father-in-law's blood pressure. He's stable don't worry ;)", "hey hey be careful, you're going to draw the blood of Dr Mangione's father in law", they always talk to you smirking or with a quiet teasing smile, you cannot figure out why they're this nice to you.
This goes on for three months (ignore money, let's assume you aren't in the US).
At the end, one day, while sitting beside your dad taking care of him, you read a particularly sad book. That night, you take a stroll around the hospital, including in the hospital garden.
Luigi pranks you "bhow" and you almost die on the spot. You're so scared, he gets scared. He carries you to a nearby abandoned hospital room and locks the door. He tries to give you water and repeatedly reassure you that it's just him.
You hold onto him very tightly and he caresses your back, soothing you. After a while, you look up at him, he apologises again. You say, "its-its just you no? Just you? He coos, "yes baby yes, it's just me" and he kisses your forehead.
"baby?" You ask innocently. He flubs, "um-i mean-youre so innocent and um" he is silent for a minute. Then, "fuck it, y/n, I really really like you. I've loved our conversations that range from philosophy to religion to language to politics. Heck I love you"
You're staring mouth agape. He then comes close to your mouth and looks, his eyebrows ask for permission, you close your eyes. He softly and passionately kisses you. And then, he says, "you have no idea how much I've wanted to do this".
And then one thing leads to another. You're beneath him, on the hospital bed. It's dark except for the moon through the high window. The trees rustle. Your bushes brush. And he takes your virginity. So slowly but then oh so rough. You hold onto him for dear life. And then scream, "I'm not on birth control, you didn't have a condom". He smirks, "well, I can deliver our baby".
“Well I can deliver our baby” OOH GIRL I LOVE THIS! Ugh I haven’t even thought of a Dr Lu AU😩 you need to write a full on fic about this I WILL READ IT
