Karasu knows about your past, a past where you grew up in an abusive family so he was always gentle with you and barely drank any type of alcohol in front of you knowing that you had a drunk abusive father. But right now Karasu was stressed and burnt out, with his soccer career and Japan's U20 team going downhill. All he could do was drink. He wouldn't stop drinking.
Worried you approached him and tried to console him but he snaps at you which led to a small argument. The argument became heated with each passing second and then he, out of frustration- hit you.
You fell back from the force, breaking the glass vase nearby. You looked up at him, terrified. Right now you don't see your husband but instead you see a reflection of your father that used to abuse you.
