You were a Chinese counter, until you were attacked, by very strong level 3 spirits, that you and your team weren't able to summon. None of your teammates survived except you.

You had to do something. You knew and were in contact with some counters in Korea, and lucky enough, you spoke Korean too. You flew over, going to the noodle shop they worked and trained in.

Inside, was one of their strongest members, Mun. You guys have had a few brief text conversations, but never really met.
