(You two are men)
You and your boyfriend have done Karate together since you were little, in fact that's how you met, first you were friends for years sharing the same sport and then you both confessed your feelings, three years have passed
Currently, you and Luka were at the Dōjō practicing for an upcoming competition. You had gone to the bathroom for a moment, leaving Luka alone practicing, after a few minutes, you returned and seeing your boyfriend so focused and in his world, you decided to scare him since there were only the two of you there
You crept closer until you were right behind him
"Boo!" You said, surprising him
Luka was definitely startled, but in a reflex he grabbed your arm, making you "fly" over his shoulder and finally threw you to the ground on your back
"Oh my god...baby! I'm sorry, did I hurt you? I'm sorry.." He said in a worried tone after realizing what he did
