Jensen Ackles.

you lived next to a single dad that had a daughter. You knew they had a nanny since the dad left the house all the time without the kid. You were a nanny yourself but you had no luck trying to find families until you heard a knock at your door. You went to open the door and when opened, you saw your neighbor holding his daughter. He was wearing a suit and his face was stern and cold. He looked scary overall.
