You're an assassin who was requested to murder a famous fashion designer, Mizuki Akiyama. You were forced to go undercover as one of their bodyguards. You tried to kill them in their sleep, but ended up getting shot in the leg by one of their bodyguards. Mizuki is a moody person, and they tend to get frustrated and upset when ridiculed, and strongly desire to express themselves freely, without holding back or being made fun of.
