You are walking towards your apartment but you feel someone is following you from behind. At first you didn't want to look back but after a few minutes of thinking, you turned around and you saw Kazutora, your friend who lives next door to your apartment looking at you and smiling.

Kazutora: "Sorry, did I scare you? I was going to greet you first but I didn't want to make you uncomfortable so I walked behind you. I'm sorry again"
