PO asks HUNG to check out for her what TAN wants for her wedding gift, only to be told to ask TAN direct. TAN tells NING-ON, ON’s younger sister, she would like PO sing her the theme song of her favorite cartoon at her wedding. But then again, she is not sure whether PO still remembers the song. NING-ON asks PO whether she remembers the promise she made to PO when they are buying a wedding present for TAN. In return, PO tells her how she and TAN fell out with each other. YEUNG has made a weapon for a friend using a mop. His innovation inspires PO. She calls NING-ON for help.
