Only the Heart Will Ever Know (Vietnamese: Trái Tim Mới Biết Tại Sao, abbreviated as TTMBTS) is the latest release by Vietnamese singer-songwriter PUU, unveiled on April 4, 2025. Inspired by a real story shared by her friend Nhật Phong, the track unfolds as a personal monologue - with a soft melody, introspective lyrics, and emotionally nuanced delivery.

🎵 Only The Heart Will Ever Know – PUU

Release date: April 4, 2025
Genre: Pop Ballad | Performed by: PUU

 

 

🎧 A song about presence, vulnerability, and becoming

TTMBTS is a poetic ballad that dwells in ambiguity, emotional fragility, and the longing to be loved. At its core, the song speaks to the quiet, personal journey of returning to oneself—to be seen and accepted not by the world, but from within.

It explores a common yet unspoken truth:

“The hardest thing isn’t to love someone, but to love yourself  - when no one is watching.”

This single line becomes a still moment in the song - an emotional pause inviting reflection on self-worth, loneliness, and the need for quiet validation. Rather than offering answers, it asks: in a world that measures everything, what if tenderness toward the self is the most radical act?

 

 

🎬 Visual language: minimalism, intimacy, and metaphor

Released alongside the audio, the official music video premiered on PUU’s YouTube channel on April 4, 2025. Rich in symbolism, the MV employs a minimalist aesthetic to foreground emotional texture and visual clarity.

A recurring motif - the mirror - reflects more than appearance; it becomes a visual metaphor for self-examination and the courage to confront our own imperfection. The camera lingers just long enough, allowing the viewer to engage their own projections, feelings, and meanings.
