It is CHI-NGO's idea to invite the ATF trainees to join their work for he wants to give them a final test. In order to rescue the hostage, YAU-CHING and YAU-KIT ignore the instructions from their supervisor. After learning that this is actually a test arranged by CHI-NGO, YAU-CHING is very upset. He tries to negotiate with KO WAI and CHI-NGO but it doesn't work. YAU-CHING and YAU-KIT believe that the chance for admission to ATF is very low. All trainees gather at the ATF headquarters to wait for the result. YAU-CHING and YAU-KIT are selected eventually because CHI-NGO appreciates YAU-CHING's ability to make quick decision during critical situations. YAU-KIT is happy for he can work with YAT-KA in the future. YAN-MEI from the Intelligence Unit of ATF discovers that YAU-KIT is interested in YAT-KA and she encourages him. KO WAI overhears their conversation accidentally and he makes a decision.
