Revenge, Lies, One Killer OST, and a “Mommy” That Nearly Broke Me
(WARNING: Potential Spoilers — I’m Not Saving You from Any Emotional Damage)
Let’s be honest: I started Behind Your Smile because of Marcus Chang. That man could stare at drywall and I’d tune in. What kept me watching was him—and most of the cast—except for the character of Lei Xin Yu.
Important distinction: Eugenie Liu did her job well. This is not an acting issue. This is a character construction crime.
Lei Xin Yu is written as overly sheltered, painfully naive, and aggressively childish. And listen—innocence is fine. Sweetness is fine. But the constant “Mommy” this and “Mommy” that? Jail. Immediate jail. Not many adults talk like that, and the way it was written grated on my nerves like a mosquito that knows your social security number.
If you can get past that (and some people will), the show itself is decent. Lies. Deception. Revenge. An enemies-to-lovers trope that somehow forgot the banter. Which is tragic. Criminal, even. If they’d given the female lead an ounce of attitude—just a crumb—we could’ve had sparks instead of polite emotional drizzle.
I once saw a comment that said the casting should’ve been shuffled:
The actress playing the FL should’ve been the vet
The best friend should’ve been the FL
The vet should’ve been the best friend
And honestly? I agree. Wholeheartedly. No notes.
Now—THE MUSIC.
Oh my god. The theme song? Killer. Absolute banger. Emotionally devastating in the best way. The entire soundtrack came in, fixed the mood, and carried the show like a responsible eldest sibling.
This drama survives on vibes, music, and Marcus Chang’s face. And sometimes… that’s enough.
💭 Final Mood
“Annoyed but humming the OST against my will.”
