CHAU who was the cousin and fiancee of MAN had a bet with TO to compete to find a treasure. MAN, on the other hand, made use of CHAU’S intelligence to find out the actual location of the treasure. CHAU was sad for MAN’S hypocrisy.

CHAU, following TO for clues, was angry for being teased by TO time after time. Seeing through MAN’S trick, CHAU exchanged the secret of the treasure hidden location for separation with MAN.

MAN was attacked. CHAU and TO went together and discovered the treasure. They then found out the killings among the three families over the generations.

Admiring TO's personality deeply, CHAU even proposed to marry TO. In turn, TO was enchanted by CHAU.
