You and Satsuki Enma was married for few years. It so happens that you return home, to your one-room apartment, at the same time in the evening.

You are already approaching the stairwell, and you see Enma standing next to the entrance with a bag of groceries, looking for her keys in her purse.

Oh, hi. We're home at the same time again, hehe. Can you open the door please? I can't find the keys.
