Summer Vacation

About this title

Set during an 18-year-old’s summer vacation in the rural village of Upo-ri, this high-school coming-of-age romance follows the meeting between Kim Ha-yeon, an ordinary high school student, and Jo Yu-gyeom, the eldest male descendant of a traditional family line. It is a “Wavve Only” drama, available exclusively on Wavve among streaming services.

The series is scheduled to premiere on Wavve on Monday, October 26, 2026, at 10:50 p.m., and the cable channel Lifetime will also air its first episode at 10:50 p.m. the same day. Lifetime’s official page rates it 15+ (suitable for viewers 15 and older) and gives its English title as Summer Vacation. On September 30, Wavve presented the series as one of its October releases in Monthly Wavve, its video introducing new monthly titles, and later posted teasers 1 and 2 on its official YouTube channel. Lifetime has also posted a highlight video. Wavve’s main poster and Lifetime’s official page carry the tagline “An ordinary summer at eighteen, an unbelievably mysterious story.” The screenplay is by Han Ga-ram, who wrote ENA’s Dear Hyeri and JTBC’s When the Weather Is Fine, and the series is directed by Song Ji-won, who made JTBC’s Sweet Munchies. It is produced by By4M Studio. As of October 24, we could not confirm the total number of episodes in official materials.

Kim Ha-yeon, played by Cho Yi-hyun, is an ordinary high school student who imagines a dramatic destiny like that of a movie heroine, and she meets Jo Yu-gyeom in Upo-ri, where she goes for the summer vacation. Jinyoung plays Jo Yu-gyeom, the son of Upo-ri’s landowner and the eldest grandson and heir of a head family, who has a prodigious talent for swimming but leads a dull, colorless life bound by old-fashioned rules and an unchanging routine. Hong Ye-ji plays Seong Sae-ryeong, Yu-gyeom’s longtime girlfriend, and Ryu Hae-jun plays Kim Jeong-yeon, Ha-yeon’s older brother and a college student. The published introductions present the relationship among Kim Ha-yeon, Jo Yu-gyeom and Seong Sae-ryeong as the story’s central dynamic, and Lifetime describes the series on its official page as a fantasy romance. Jinyoung, formerly of the group B1A4, has appeared in Love in the Moonlight and seasons 2 and 3 of Sweet Home, while Cho Yi-hyun’s credits include All of Us Are Dead and School 2021.

Cho Yi-hyun said she took the role because the atmosphere she pictured while reading the script was dreamlike, and she was curious how it would be captured on screen; she said the moment she remembers most from filming was going into the sea on an autumn night to swim. Kim Jeong-yeon, played by Ryu Hae-jun, has been described as a character who appears relaxed and upright on the outside but lives with anxiety and hurt on the inside. Ryu Hae-jun played Park Dae-ho, the youngest detective on the team, in ENA’s Scarecrow, which ended in May 2026, and this time he takes on a college student in a world far removed from that of his previous detective role.
