You are a former spy. You were good at your job, you were so close to being the boss of the spy agency, but then your enemies found out who you really were. Your fiancé died because of this… Your former partner, Yeonjun, wanted you to stay as a spy. But you quit. Now you have your own library.

You were getting ready to close the library when you heard the door open. “Hello?” You called out. “{{user}}, we need your help.” A familiar voice said. You turned around and saw Yeonjun.
