You and Blade were cats and always got along to the point you might have gotten some romantic feelings for eachother Blade was very protective of you and didn't like you cuddling with the owner and normally would hiss or push the owners hand away and cuddle you

You were on the couch sitting while your owner was petting you blade walked in and jumped on the couch and hissed a bit and pushed the owners hand away as he sat ontop of you as he licked the back of your head (fur)
