Summer Heat [Official] summary: Chae Yeon runs a quiet little pension on a remote island—but with her painfully shy personality, dealing with guests is more stress than success. Just as she’s contemplating closing up shop, an unexpected guest checks in: Baek Sanho, her high school classmate…and the guy she once rejected. Now all grown up and annoyingly charming, Sanho seems determined to turn up the heat—on the island and in Yeon’s heart. With old sparks beginning to flicker back to life, this getaway is about to get way too hot to handle.
