만약에 (옥탑방 왕세자 OST)

Lee Seok Hoon's "만약에" is the kind of ballad that builds its emotional weight through accumulation rather than explosion. The arrangement begins with just piano and breath, unhurried, as if the singer is working through a thought in real time. Seok Hoon's tenor is polished but never cold — there's a trembling quality near his upper register that suggests vulnerability being carefully managed. The song poses the central question of counterfactual love: what if things had gone differently, what if one moment had pivoted another way. By the time the full orchestration arrives — strings, light percussion — the question feels almost unanswerable, which is exactly the point. This sits comfortably within the tradition of Korean drama ballads that treat longing as a kind of spiritual condition. It's music for the commute home after a day that reminded you of someone.
