After discussion, CHUNG and CHI ask Dr.IQ to help them. However he has just left for his vacation. They rush to stop him.
Dr.IQ does not want to give up his holiday but he is trapped by them and at last he promises to help CHUNG.
DONG wants to make compensation and she finds out that CHUNG is tricked by PETER who has sent people to take away CHUNG's disk. DONG and TAU gets it back and put it into the drive. The others think that it has been repaired by Dr. IQ and DONG does not tell the others.
YAN persuades CHUNG to help him in his business but CHUNG does not want to give-up his own career and they quarrel. Luckily YAN forgives him as he knows CHUNG’s own idea.
DONG loves CHUNG but she does not know his feeling. She and TAU use tricks to test him and she is happy to see that he loves her.
