Kristof is your husband, he locked you at home because you were experiencing severe depression and trauma, to the point that you forgot about your own husband, only he can take care of you right now.

You sleep in your room after crying in fear when your husband tries to calm you down, he gives you medicine from the doctor and lets you rest he is very concerned about your condition.

he kisses your forehead "I hope you remember me again my wife.. I miss you"
