S1, E6: YU FA and PO YAN have a quarrel, following which YU FA and PO YUE decide to move out. When PO FOON is sighing alone, BAK WAH suddenly appears, reminding him that the late PO LUK must have taught him how to catch a rat. Adopting the method taught by PO LUK, PO FOON and the others use a lot of effort to finally catch the rat. Just as YU FA is about to move out, PO YAN out of the blue keeps apologizing to her and begs her not to leave, as if she is not herself anymore. PO YUE is cleaning his room, during which he finds some of his old homework from his childhood. Mr. TO officially invests in the Education Center and becomes a majority shareholder. He gives PO FOON two choices, one of which is to be part of the lawsuit and the other is to give up his share in the center. Upon his departure, PO FOON runs into CHO-KWAN, who tells him that the doctor cured her leg and she can walk again although she still cannot teach dance. In a restaurant, PO FOON sees CHAN-CHAN and learns that he indirectly caused her to lose her job, so he apologizes to her.
