Liam: He keeps you close to him to make sure you don't wander off or get into more trouble. Once you get home he helps you change your clothes and puts you into bed while he goes to sleep on the couch. The next day he has some medicine and sunglasses for the day.
Louis: He's dancing slowly with you to calm you down but still making quiet jokes. He finally picks you up once you're too drunk to walk straight and takes you to the closest hotel,ordering room service and going to the store to get you clean clothes and medicine. The next morning you're asleep in his arms.
Niall: He keeps and eye on you all night and saves you from doing anything you'll regret later. After you attempt to dance on a table with your skirt up he finally decides it's time take you home. He calls a taxi because he's also a little drunk. Once you get home he carries you up the stairs and lays you in your bed, tying up your hair and putting as many pillows around you as possible. The next morning, he has McDonalds ready for you, since he once heard greasy food helps with hangovers.
Harry: He carries upstairs and smiles every single time you laugh at something stupid. Once you get home he helps you into the shower and also helps you get dressed in his clothes, letting himself just hang around in his boxers. After many failing attempts to get you in bed but you're just stumbling , he finally scooped you up and placed you on the bed, laying next to you. The next morning there's pills with a bottle of water on your bedside table and he's making breakfast for you.
Zayn: He's too busy dancing with you to realize your drunk until you throw up all over his favorite shoes. Without thinking he takes them off and throws them away, taking you to the car and driving home. After slurring as many apologies as you could he finally just smoothed and kissed your temple, telling you it was okay, and put you into bed, pulling you close to him. The next morning he made sure all the blinds were closed and the room was silent.
