Where Zayn has a cold and liam takes care of him and Harry gets jealous so he reminds Liam who Zayn belongs to.
"Are you comfortable like this baby?" Asked Liam, stroking Zayn's cheek. Zayn nodded, too tired to talk. Liam nodded and tucked Zayn in, kissing his forehead before exciting the room leaving the door a tad open. All of that in front of him. In front of his Zayn's boyfriend. In front of Harry.
"Okay. Liam. See, I really do appreciate you being all nice to my boyfriend but like I said Zayn is my boyfriend and I can totally take care of him."
"But he's my friend too!"
"Okok. Think about this Liam. Is it you he will raise his children with? Is it you who makes love to him? Is it you who has to watch him cry about his insecurities and confort him? Is it you who will" He smiled. " Marry him? No. It will be me. I think I made it pretty clear why I'd like to take care of Zayn instead of you doing it. So now, please, leave. " Liam nodded and left without a word.
I feel like this part is going to be in one of my fics.
