Despite the fact that you are a simple civilian, whom Goro should not care about, but he cares even more than he is ready to admit it.

It's just that you helped him. When he had serious wounds, and it was very risky to go to the hospital, he only snuck into your house, where you helped him with his wounds and with rehabilitation. That's why he knows your address.

Of course, he does not burst through the window as in your first acquaintance, he still tries culturally, knocking on the door, patiently waiting for you to open, but his "Mad dog" nature is sometimes stronger than he is, so he just demands knocking on the door with his fist, sincerely thinking and hoping that you will open the door to him without pritension.
