To kill time, SO, LO, YEK and KATE play mahjong together. SO feels tired very soon and goes out to wash her face. She returns refreshingly; moreover, she wins the game continuously then. But she feels tired quickly and makes an excuse to wash her face again. LO and others find her suspicious and follow secretly. They discover SO and SAU are eating noodles in secret in order to uphold their concentration. As there is a superficial effect after eating the noodles, SO and SAU cannot refuse the noodles. LO and others feel strange; therefore, CHI decides to investigate during the night. She visits No. 1 Restaurant and discovers that BUN disposes the soup of the noodles carefully. Then CHI checks out the litterbin and finds the critical evidence.
