The best revenge for Mikan Yukihira is to annoy the hell out of Natsume for a living until he truly apologies for what he did and said. As for Natsume, he's purely baffled by Mikan's too vivid attire, quirkiness and Pollyanna POV towards work and mainly HIM. All seems well but suddenly, the plan seems to backfire on her as Mikan finds herself falling for her new, hot and cold boss.
