Scruffy Dude
He's a total cuddlebug. He just wants to curl up and watch movies while snuggled with a lover on the couch, or he'll come up and wrap his arms around them and kiss them on the cheek. He also loves cooking, and he will pour his heart into making their favourite things if he's smitten.
The Merry Maiden
She really likes sharing activities she enjoys, exploring unvisited places, and just spending quality time with a lover. She's a lot softer, less guarded, and may even become a little flustered.
Glitch
She's ace, but when she wants to be good friends with you, she'll just hang around you a whole lot. If she considers you a super good friend, she'll do things like sit on your shoulders uninvited, drop her whole body weight into your arms without warning you first, or otherwise get all up into your personal bubble.
Boxer
Holding hands, leaning on his partner's shoulder, and patching said partner up when he does ridiculous daredevil stunts. (Boxer has long since stopped trying to convince said partner not to be crazy and reckless.)
Blues Scale
He likes physical touch, but tends to reserve it for special moments. He becomes protective of someone he's falling for. He'll look out for them, do little things for them, and want to spend a lot more time than usual with them.
