Irin is said to be hot-tempered and fearless – "The Devil". It’s all an act, though; in reality, she puts on a mean front to protect her younger sister, Inn. However, her young vet and neighbour, Namcha, couldn’t care less. No matter how spiteful she behaves, his love endures. He has loved her since they were students and has no intention of changing his heart. In fact, they were dating until Irin called it off without any explanation. Namcha has never forgotten his first love, but Irin doesn’t believe his feelings have remained the same; Namcha makes it his mission to prove it to her. Love should be easy for the two of them, but family, work and even friends all seem set on tearing them apart.
