Newt:
Newt isn't in to too much PDA, mostly just little kisses on the cheek here and there, but he won't hesitate to kiss you in front of the other Gladers so they don't forget you're his.
Thomas:
Thomas loves PDA. He's constantly holding your hand and giving you surprise kisses. The other Gladers find it really annoying but none of them even think about making a move.
Minho:
Minho isn't a huge fan of PDA. He'll put his arm around you in front of the guys but not much else than that. He saves the kisses and stuff for behind close doors. It can get a little heated if you know what I mean ;) (I felt so weird writing that just FYI) You've gotten a few hickeys a couple of times
