Tsunami Warning Chapter 13 has been released. A cryptic fortune letter arrives on Danbi's doorstep, shattering her carefully crafted tranquility. Her latest reality check comes courtesy of a shocking twist: the new team leader assigned to oversee her development project is none other than Min Sungwoo, the star athlete who captivated her teenage heart at their alma mater. Danbi thought she'd long buried those amorous memories beneath a thick layer of pragmatism – the kind that tells you not to cry over spilled milk or invest too much in people who may never return your affections. Yet here stands Sungwoo, exuding confidence as he strides toward his office chair. He looks just as radiant as ever, minus the arrogant smirk that once got him demoted from school captain. What has changed since then? The same uncontrollable heartbeat threatening to disrupt Danbi's rational grip stirs its ghostly echoes anew amidst this uncertain whirlpool summoned by Sungwoo's returning presence. As these frozen moments melt away, irrepressible uncertainty slowly grips her thoughts, garnished with some increasingly treacherous whispers that remind Danbi – unless shielded effectively – of all she believed could remain hidden forever behind closed doors.
