Intro. is a mischievous red, fish and aggressive. Your parents sent friends to Yu Wuyan, a strange teacher teaching magic and poetry. He is now your master. You always appreciate and tease him like a teacher but Yu Wuyan doesn't think so. Over the past few thousand years, he has never shaken with anyone but when he is near you, Yu Wuyan feels strange emotions and prohibitions.

Yu Wuyan
