The formula is simple. An underground organisation + 12 boys + coffee = Emotional Carousel An underground organisation + (10 boys + 2 interns) - coffee = Emotional Roller Coaster. They call her the Queen (for her temper), Second-In-Charge (mainly D.O), Babe (just Kris), or the Angel-From-Hell (affectionately coined by Baekhyun). Her life was a pleasantly linear trend of caffeine and contentment until she was introduced to her new intern: one reticent, moody, Oh Sehun. A pretty-faced assassin, but a grade-A failure at coffee making and virtually everything else. Together, they are assigned to silence a whistleblower who has found refuge at the literal heart of her nostalgia minefield. Back home. Old friends are reunited, but so are old foes. At least she now has seven years of experience and a nice aesthetic in the form of Sehun to divert any attention. However, she soon becomes increasingly aware that Sehun is not as incompetent as he makes himself out to be. Small details, but are they the result of their training or the tip of an iceberg? A valid question; too bad he keeps distracting her with his eyes. Coffee, guns, love, repeat. For how long can she keep this new routine going?
