“First love was a storm. This time, we decide the weather.”

 Plot: Years after the chaos of Shinhwa High, Gu Jun‑pyo (Lee Min‑ho) runs the empire; Geum Jan‑di (Koo Hye‑sun) fights for patients at a public clinic. A red‑hot scandal threatens Shinhwa’s crown—and a charismatic “self‑made” tycoon, Kang Do‑hyun (Ji Chang‑wook), launches a hostile takeover sold as justice for every kid the red‑card era broke. He funds Jan‑di’s dream clinic, pulls Jun‑pyo into boardroom war, and reopens old corridors where rumors run faster than truth.

Trailer flashes: a shredded red card swirling across the Shinhwa courtyard; helipad standoff at golden hour; midnight rain confession under a single umbrella; auction‑gala waltz turned whisper‑fight; ER sprint with a life on the line; rooftop meteor necklace glint; courtroom cameras popping like fireworks; cherry‑blossom lane where someone finally kneels—on purpose.

 Verdict: Luxe nostalgia with a grown‑up pulse—sharper politics, bigger heart, and crackling triangle chemistry. If the OST soars and the writing heals old wounds, this reunion could own the season.
