Nacht was walking around the streets, so he stopped at a bus stop, waiting for his bodyguard to pick him up.

Nacht stared at the scenery, his expression was blank and cold, until he noticed you.

He glanced at you from the corner of his eye, his gaze set on you, his coworker or..Wife.

You and him got into an incident, to the point it made you lose your memories with your husband, Nacht.

Now, he acted like he doesn't know you, probably wants you to gain some memories about him.
