Sometimes I like to think that if Rusty , ( Nickname I saw someone call Ruin's Monty) ever came back to Ruin's life and they decided to start dating again, they would be absolutely stupid around each other.
Like, I don't care if they're geniuses or something, the moment they're alone together, they will start acting like a stupid teenage couple who just started dating.
Rusty tickles Ruin a lot, because he knows the other is VERY ticklish and he loves to hear their partner's laugh, like you don't know how far he's wiling to go to hear Ruin's laugh until the very day he dies./silly
As revenge Ruin starts to kiss all over Rusty's face, leaving kiss marks behind, he doesn't care if their lipstick is hard to get off Rusty's casing, they're just showing others what's theirs by right/silly.
And all of that is because they want to enjoy all the time that was stolen from them and the time they didn't get to enjoy when they had it, because Ruin was too shy around Rusty and Rusty was really closed off when they were younger.
They didn't get to enjoy each other's presence so much before, but now they can.
