The ABEMA original production “Bakansu no Housoku” (Japanese: バカンスの法則, English: The Vacation Principle) has not only received an official main trailer but also announced the opener for the series. As the streaming service announced on July 21, 2026, the K-Pop group ILLIT will provide the opening melody for the drama with their new song “I Got Your Back.”
The song is the title track of the second Japanese single by the five-member girl group, which will be released digitally on July 26 and on CD three days later. “I Got Your Back” is a rock-driven, energetic track about sticking together in difficult times—a fitting musical start for a story described as a “detox romance.”
The series begins on July 27, 2026, at 8:00 PM on the ABEMA SPECIAL channel and will be broadcast exclusively on the platform. Each episode is 15 minutes long, with a total of 18 episodes planned. It will air every Monday, Wednesday, and Friday at the same time—an unusual short format designed to appeal primarily to busy viewers.
At the center of the plot is Midori Hoshino (played by Kanna Hashimoto), a woman who suddenly finds herself jobless after losing her position at a beauty clinic. On the advice of her brother Kanta (Ryo Katsuji), she retreats to her late grandmother’s vacation villa to take a “break from life.” At the idyllic seaside estate, she meets the mysterious caretaker Nishigami (Chae Jong-hyeop), who exudes an enigmatic atmosphere. A tender love story develops between the two, but a dark secret lurks behind the cheerful facade.
Other main roles are played by Mizuki Yamashita as Rinrin, Aiko Kanou as Tsumugi, and Dori Sakurada as Tetsuro. Creative responsibility lies entirely with the renowned manga artist Akiko Higashimura (“Kakukaku Shikajika,” “Tokyo Tarareba Girls”) for the first time, who not only conceived the original concept and wrote the script but also directs—her debut as showrunner of a live-action series.
The now-released main trailer offers a first comprehensive look at the blend of comedy, romance, and mystery. While the opening scenes show the chaotic cohabitation of Midori and her brother in the villa, the mood shifts over the course of the video: A tarot card reveals the word “DEATH,” Nishigami looks troubled on a stormy night, and Midori asks in the rain, “Who are you?” The production promises an emotional rollercoaster that aims to make viewers laugh and think.
