Overview: ON and KEI have done a body check-up earlier. The family is surprised to learn that it is not KEI who has health risk. PO and ON forbid ON to eat anything other than vegetables for dinner. PO also demands that he stick to the diet and fitness plan she has worked out especially for him. She keeps a record of the total miles he has run, too. ON turns to WAN for help. Before she goes out to the wet market, PO tells ON to run two km. WAN shows up with COFFEE as soon as PO has left home. ON is working overtime. PO checks up on him by making a video call. Obviously he is well-prepared. NING-ON finds that something is wrong with the screen of the video phone. PO cannot help but suspects that ON has not followed her diet plan.
