MacCready is a total cuddler. When he and the SS finally get together, he doesn't even bother to hide how important and how special they are to him. He will scoop them up into his arms and nuzzle them and pepper them with soft kisses until they fall asleep, whisper sweet nothings into their ears and brush his fingers through their hair. He feels so close to them and comforting them makes him happy, to return the favour after everything they've done for him. He will hum the SS's favourite song from the radio as a lullaby if he has to, he'll let the SS rest their head on his chest/stomach when they're relaxing and just enjoy playing with their hair. Every chance he gets he will hug the SS, give them a kiss on the cheek, steal a kiss from them in any way and always pull them close and cuddle them at night.
