"My Yifan and Sang Yan heart"- Fans in a frenzy as TXT's Soobin covers The First Frost OST at the group's Macau concert
TXT began the Macau portion of their 2025 world tour, ACT: PROMISE—EP. 2, on May 9, 2025, with a surprise for the audience. Mid-concert, leader Soobin took the stage to perform a solo number, singing Silence Wang's 像晴天像雨天 (Like a Sunny Day, Like a Rainy Day).
The emotional ballad served as an OST for the popular 2025 Chinese drama The First Frost, a prequel to the 2023 success Hidden Love. The series, based on Zhu Yi’s novel, starred Bai Jingting and Zhang Ruonan as Sang Yan and Yifan—characters whose tender romance left a lasting impact on viewers.
