Sayako- She'll curl up in the person she's cuddling(in this case, matt)'s lap, usually, humming and holding their hands gently as she presses occasional kisses to their hands. She basically goes soft and nuzzles them, most of the time she'll fall asleep.
Sora- She'll either spoon them or cuddle them while hugging them. She likes to put her head on their shoulder, humming/singing softly. Additionally, she loves when Mimi plays with her hair and hums along with her.
Tai- He prefers to be held, cradled, spooned. He likes when Mariah coos at him, though he will never ever open up to that, because he's THE Tai Kamiya, who doesn't need attention.. or cuddles, he's a strong boi who doesn't need a GIRL to make him feel loved.... Yeah, he denies it, but he desperately needs it.
Matt- He either holds sayako in his lap, cradles her in his arms(he's a strong boi-), or has her lying on top of him. All of these have the two of them getting equal amount of affection.
Hitaru- He likes to be held by his partner, and will wrap his arms around their neck. He really likes when his partner kisses each of his freckles(his face is COVERED with them) and whispers something they like about him. He'll blush like crazy.
Izzy- He likes anything. He's okay with like, every cuddling position. He really likes sweet-talking his partner, and especially likes it when they do it to him.
Kari- She'll hug TK with her arms around his neck, putting their faces close togther. She doesn't usually initiate this, but it makes her flustered AF, which Tk finds absolutely adorable.
Cody- la smol spoon. he'll be close to falling asleep, and unless he's stressed or tired, Yolei will kiss his neck gently, sending him wide awake again.
TK- He'll wrap his arms around Kari's waist and pull her close so that their faces are really close. He loves seeing how flustered she gets; he finds it adorable.
Yolei- She's the big spoon. She likes to snuggle Cody and get him sleepy enough to the point where he nearly falls asleep, and unless he's upset or tired, she'll kiss his neck so he's wide awake and extremely flustered. She does this many times.
Mimi- she likes it specifically when Sora cradles her in her arms, and even more so when Sora sings softly to her. It's calming and Mimi falls in love all over again.
Davis- He likes sitting in Ken's lap, and eventually ending up laying on top of him until they have to leave or they fall asleep.
Ken- He likes to lay down and pull davis on top of him after Davis was sitting on his lap. He'll wrap his arms around Davis' waist and stare into his eyes.
