NIC feels that he should quit studying and look for a job to share the burden of his mother, who is a poorly paid cleaning lady. On the contrary, SUN’s mother is a famous doctor, who is about to go abroad for a medical conference. Back at the school, CHING is allowed to join the beach volleyball team. KIT has seen KIU play before and invites her to join the team. However, She turns him down because she does not want the training to affect her work in the first aid team. KIT does not give up. He thinks of a way to move her. The school promotes a Cookie Day to encourage girls to make some cookies for the boys whom they like. The sisters work hard to make some cookies for CHING to give to SUN. CHING brings the cookies to meet SUN, but they miss each other. She is even chased by a dog and drops all the cookies.
