In Episode 19 of Coffee Cat Mama, Ah Yum (Vincent Wong) and So Mei (Nancy Wu) break the ice on the bus. So Sic (Jerry Koo) calls So Mei to tell her to express her hidden love to Ah Yum and then calls Ah Yum to let him know that So Mei has only been sleeping in the living room. But, this causes a conversation to go wrong. Because So Mei thought that So Sic had told Ah Yum that she likes him, and Ah Yum asks So Mei to move into his room, So Mei thinks that Ah Yum is trying to ask her to be the third wheel in his relationship with Fei Fei (May Chan).
Ah Yum: So Sic told me everything already. Although we did have an argument before, you can still tell me.
So Mei: What argument? You called off our friendship! Last time you came to pick up Bao Jo Gong (Alvin Lau) at my place. How would I dare to talk to you about my matters?
Ah Yum: Do I seem that stingy to you?
So Mei: That means you want to… But didn’t you promised Fei Fei that you were marrying her?
Ah Yum: Me marrying Fei Fei and the two of us are two different matters.
So Mei: Two different matters?
Ah Yum: Yes. After marriage, I plan to move to her place, so you can move into my room.
So Mei: Huh? Are you serious? You plan to…
Ah Yum: Include. Of course! I’m sure that since everyone is so close, living together should not be a problem.
So Mei: But Fei Fei…
Ah Yum: No worries. She mentioned before that she does not mind. As long as it is something I want to do, she won’t oppose of it.
So Mei: I think that she might say that, but she definitely does not feel the same. No one can be so generous.
Ah Yum: Fei Fei is a very good girlfriend. She will definitely not be jealous. In the future, we can come visit, and you can come visit us too. If you really feel it’s awkward, we don’t always have to be a group of three. But, as you are living at my place, I will definitely take the responsibility. You can call me anytime, of whatever needs you have.
So Mei: Although my brother told you about my matters, that does not mean you can think of such a solution!
