I love "Threesome"! This is a really nice TVB drama and I enjoyed it from the first minute to the last. It is a light-hearted take on multiple personality disorder (and others such as anxiety, suicidal thoughts etc.) and how such a mental disorder affected the lead's life. Unlike other similar shows like "Kill Me, Heal Me" (Which I feel had a darker tone based on the snippets I saw), this drama is more comedy-like, and I was laughing throughout the show. The drama also had sweet romantic elements between Kai and Evie - showing how they became closer in the process of Kai helping Evie to hide her secret. I thoroughly enjoyed this drama, and found new things that I had not noticed before when rewatching. Anyone looking for a refreshing psychological drama would find this wonderful.

Production/Story:
The story was well-paced, engaging and funny. It used a comedic way to explore the adverse effects of how having a psychological condition can affect one's life. I really liked how Kai and Evie's relationship progressed too. There were so many funny/touching scenes, like how Pina Colada married Dominic, and Evie had to deal with the situation, or when Evie's mother finally reconciled with her (I cried...). In short, wonderfully written!

Acting:
This show was such an acting breakthrough for Mandy and Ben. I feel that their acting abilities were really put to the test and they showed me how great their acting was. Not to mention how much effort they put in. For example, in an interview of Mandy, she mentioned that she only slept 1 hour ever day while filming the show as she had to act 3 "characters". Ben also really entertained me when he had to act out Evie's different personalities in place of Evie to ask Dr Bean how Evie should be treated, I've never seen him act like that! Other than that, the supporting cast was pretty okay too, they acted out their roles well, the only shortfall being Arnold who I felt was quite stiff in his acting, but I'm sure he can improve.

Music:
I love the opening theme song -《无双》by Miriam Yeung. Mandy and Kinlas even have a special choreography for this dance which I went to learn, although I don't have someone to do it with me, oh well. I also went to download its piano score, that's how nice the song is, full of meaning and really suited for the drama.

Rewatch Value:
Would definitely rewatch this again, I've already done so once and found some details that I missed out. I feel that this drama is that kind of show where you'll find something new or have new reflections when you rewatch, so this is definitely high on my rewatch list.
