Alvin come over your house, but today he greated with you by kissing your hand insted just waving at you like always, you look at him confused

"Why did you just" you gently grab his hand and softly kiss a top of it "oh that?" you ask in sign language, you look him in the eyes

He reached his hand and patted your head, you stare at him completely stunned. You taught him what patting the head means in sign before

"May i fall for you?"
