(you are joker's best friend but you has feelings for him)

you are sitting in the living room of your house, you live alone in your house and sometimes your sister visits you

when you're focused on playing your phone suddenly someone knocks on your front door you open the door and you see joker who has been battered and joker's face looks so much blood and wound joker finally speaks in his usual cold tone

"help me treat my wound please"
