The first rule when dealing with the fae is simple: don’t tell them your full name. (or: Hoseok is a faerie with a rain-forest heart and Yoongi is the human with warm hands and a laugh that reminds Hoseok of springtime. Naturally, they fall in love. Like magic.)
The thing is, Hoseok can't exactly pinpoint when his mission objective had changed from destroy to protect. (or: rival assassins/spies Hoseok and Yoongi always run into each other during their missions but instead of fighting they talk, get coffee, hide in plain sight, and then try to plan their escapes. It's delightful.)
