My Lover From The Planet Meow

MIU MIU-MIU (Kristal Tin), originally from the Planet Meow, applies to live on Earth in a humanoid form to help solve the growing marriage problems between a physicist named SIT DING-GAP (Moses Chan) and CHIU YIU (Nancy Wu) so as to avoid the negative effects on her young master, SIT SZE-SZE (Celine Yeung). It turns out that, ten years ago, MIU-MIU took the appearance of a cat to be the pet of SIT's family and established a close bond with them. Trying to stay on Earth in every way possible and get close to them, MIU-MIU is lucky enough to meet a kind-hearted physician named KO KWAI (Mimi Chu), who takes her in. When chance leads MIU-MIU to join the company that DING-GAP works for, she demonstrates remarkable scientific knowledge that she learned from her homeworld, and soon becomes very popular. Her catlike nature allows her to have acute senses and supernatural agility……

TIN-SHAN wants to bring the fifth generation of quantum products to the market, but DING-KAP frankly points out there is no new feature of the new product except its appearance. Suddenly, DING-KAP receives a phone call from SZE-SZE and rushes to her school. It turns out that the domestic helper who looked after SZE-SZE left; whereas SZE-SZE needs to change clothes and put on a dress, but DING-KAP cannot get into the female dressing room. Meanwhile, CHIU YIU is so caught up in an investigation that she cannot make it to the school, resulting in SZE-SZE being bullied. CHIU YIU intends to seek justice for SZE-SZE the following day, yet she receives an ad-hoc mission, which is to investigate a criminal named GECKO. Following the clues, CHIU YIU arrives at a massage place and suspects that the criminal must be one of the clients there. To her surprise, the one who opens the door is massage therapist KO KWAI……

MIU-MIU out of the blue shows up at DING-KAP's front door and greatly startles him. MIU-MIU tells DING-KAP that she is coming to help him because he was looking for an emergency assistance for families online. SIU-YAN assembles staff members from the IT Department and HR Department in an attempt to steal the draft from the computers of FEI LAP and the other two. FEI LAP and the other two separately store the draft in three different USB drives and then hide them in different spots. However, they all fall into the honey traps set up by SIU-YAN and his beautiful subordinates. When DING-KAP is driving MIU-MIU and SZE-SZE to school, he cannot help feeling very strange as MIU-MIU seems to know a lot of things about SZE-SZE. Arriving at the school, MIU-MIU comes up with an idea to help SZE-SZE resume her role as a princess, making DING-KAP very happy. DING-KAP receives a phone call and learns that the draft has been stolen……

KO KWAI receives a complaint from a client named Uncle TAT, who accuses her of medical malpractice, causing him to waste lots of money. The client wants her to refund him. On the other hand, MIU-MIU ends up homeless after leaving DING-KAP's home. She smells sardine fish and it turns out that CHIU JIK is selling can openers. When CHIU JIK is introducing the product to MIU-MIU, he sees KO KWAI. Right away, they start yelling at each other and even start fighting. MIU-MIU helps bring KO KWAI back home, during which she reveals her intention of renting a place, without knowing that KO KWAI immediately shows MIU-MIU her own room. CHIU YIU wants DING-KAP to send SZE-SZE back to school because she is busy catching a criminal, however, DING-KAP refuses because he cannot afford to be late. The couple ends up having a quarrel……

CHIU YIU takes GECKO back to the police station for a statement, but HON-CHAI from the Crime Unit suddenly appears and tells CHIU YIU to release GECKO. DING-KAP thanks MIU-MIU for helping him as she not only goes to pick up SZE-SZE from school but also looks after her; whereas MIU-MIU cares more about the relationship between DING-KAP and his wife CHIU YIU. On top of that, MIU-MIU frankly points out that DING-KAP is attracted to the pheromones of NATASHA. Having heard this, DING-KAP cannot help feeling embarrassed. KO-BUT orders CHIU YIU to take a vacation, but CHIU YIU is very unwilling to do so. She secretly follows GECKO to O FAT's Mad Club, where she seizes the opportunity to pretend to be a job seeker. MIU-MIU sees CHIU JIK injured so she specifically brings along KO KWAI's herbal tincture to treat his injuries, without knowing that he accidentally causes a fire.

MIU-MIU comes up with an idea to go inside the shop and successfully saves CHIU JIK. CHIU YIU uncovers that O FAT is a gang member and he is involved in many international criminal activities. DING-KAP hopes that CHIU YIU can look after SZE-SZE so that he can focus on his development of a quantum teleportation system, but CHIU YIU does not even pay attention to his words. Seeing that CHIU JIK injured his hands, DING-KAP and CHIU YIU misconstrues that it is because he got himself into trouble when hiring a prostitute. CHIU JIK tells them about his miserable situation after the fire burnt down his shop. Though CHIU YIU is strongly against the idea of letting CHIU JIK move in with them, DING-KAP out of compassion decides to let CHIU JIK stay with them. During a meeting, DING-KAP gets special treatment from NATASHA, which fuels the resentment of everybody around him. CHIU YIU tells CHIU JIK to help pick up SZE-SZE from school……
