who promises to help keep her hidden, and the two becomes friends. After this encounter, Miss Yuen becomes obsessed with finding and catching this "big fish", enlisting the school's principal (Kent Cheng) and other friends to her cause. Siu-may and Chi spend time together and become close. Chi discovers he can swim now, which is due to the pearl in his stomach; he and Siu-may swim together in the school pool, with Chi agreeing to be blindfolded when Siu-may claims she doesn't have a bathing suit. Siu-may decides that the best way to get her pearl back is to kiss him. After a dinner date together eating clams, Siu-may gets the chance, but she is so caught up with her new feelings for Chi that she forgets to summon the pearl. On Chi's birthday, he confesses that he has feelings for her, and Siu-may protests that he can't, because she is a "fish". Siu-may stands under the rain and allows herself to transform into her mermaid shape. Chi falls down in shock, and at that moment Miss Yuen and her colleagues run in and capture Siu-may, carrying her away. Chi, Kenji and Kiki work together to rescue Siu-may where she is being imprisoned in the principal's swimming pool. They are successful, and they return to the docks the next morning. Siu-may has her pearl now and can return home. Chi and Siu-may declare their love for each other, and Chi adds that he'll wait for her. Siu-may jumps into the sea, transforms and swims away. Afterward, Miss Yuen, the principal and the rest of their group follow Chi around in the hopes of finding Siu-may again. One day Chi bumps into a bridesmaid at a wedding, who looks identical to Siu-may. The principal takes a hose from a nearby gardener and starts spraying the new girl, but she doesn't transform into a mermaid, much to their confusion. The grown-ups are then chased off by Kenji and Kiki. The new girl doesn't appear to remember Chi, but when he invites her to eat clams she gets excited and lets slip that she is, indeed, Siu-may. The pair embrace while Kenji and Kiki watch. Cast Ekin Cheng as Chi, a young teacher at a high school, he was saved from drowning twice by a mermaid, and eventually falls in love with her.
