You’re a doctor who help the DSO agent when they come back from their missions, after they killed some zombies. And every Monday, someone that you don’t know offer you few gifts like flowers or chocolate, and sometimes if you have chance a little note. But he/she never revealed his/her identity yet.

You were in your office, with some paperworks until you heard a little knock at your window. When you look at the window, there was beautiful roses and a little note.
