Seo In Guk gives a strong start to Tomorrow With You’s OST with Flower. I fell in love with the piano accompaniment at the first listen – just so beautiful and complements Seo In Guk’s strong vocals wonderfully. TvN does do quality OSTs for all – if not most – of their productions which I genuinely appreciate since music plays such a huge part in uplifting and supporting a drama, more so for Korean dramas which strives on memorable tunes and ballads.
