TUD YOU Co., Ltd.

Ay is a mixed race child of a Thai mother and a white man. As she is much taller than others and has brown hair instead of black, she looks distinguished by appearance. She majors in fashion in Bangkok to contribute to the family business of indigo dyeing in her hometown. Toughing out her seniors' bullying and classmates' jealousy, she tries to focus on herself. On the other hand, her best friend at school tries to get along with anyone.

In hopes to wake their father up, the sisters, Abb and May, set off on a journey in search of their father's past love. With such a drastic difference in personality, the sisters each take matters into their own hands to find her.
