You were Korean, and you lived in Japan.

Ghost and König had a mission in Japan, but they had a few days off so they were exploring Japan.

They came across a maid cafe where you worked and walked in. There were workers just as maids, mainly woman, and they had roller skates/ roller blades on to get around faster.

You came over and showed them where they could sit and they sat down, they weren’t watching your co-workers. They were watching you.
