B1A4's Jin Young Plays a Swimming Heir in Teen Romance 'Summer Vacation' on Viki

B1A4's Jin Young leads Summer Vacation, a teen romance drama opposite Cho Yi Hyun that premieres October 26 and will stream on Viki.

Soompi reports that Cho Yi Hyun plays Kim Ha Yeon, a typical high schooler who goes through something mysterious over her break before coming back to reality. She trades the hurried city for Upo, a rural village where life slows down, when she joins her father on a work trip.

Jin Young plays Jo Yu Gyeom, who is Ha Yeon's age. He is the son of Upo Village's landowner and the eldest grandson of the head family, a striking young man with a rare gift for swimming.

Bound by his traditional family's strict rules, Yu Gyeom has been drifting through a repetitive, joyless routine. Meeting Ha Yeon stirs feelings he has not felt before.

Hong Ye Ji plays Sung Sae Ryung, Yu Gyeom's girlfriend of many years. She is far from happy about Ha Yeon turning up, and she ends up central to how the story unfolds.

Upo looks calm on the surface, but the drama layers in a quiet thread of mystery and slow-building suspense beneath its peaceful setting.

Jin Young said the script felt nostalgic from the start: "When I first read the script, it felt like I was looking back on memories of midsummer." The role also kept him in the water for much of the shoot. "I spent so much time in the water filming this project that I feel like I've done all the swimming I'll ever need to do in my life," he said.

Cho Yi Hyun credited her co-star with setting the tone on set:

"He truly took great care of me on set. We also talked a lot, and thanks to his attentively taking the lead, we were able to work together comfortably."

She picked a night scene of the two swimming in the autumn sea as a standout memory from filming.

Cho Yi Hyun also appears as Moon Hye In in the film Final Interview, which reaches theaters November 4.
