South Korean girl group Loona (stylized as LOOΠΔ) has released a cutesy new video featuring an overt lesbian love story.

“'Heart Attack' does not interpret the feelings of being in love in a serious way, but with Chuu’s own adorable emoticon-like ways,” reads an official description of the K-pop bop. “The music video has references to historical and fictional figures such as the artist René Magritte, Hans Christian Andersen’s short story The Little Match Girl, and John Appleby’s novel Aphrodite Means Death.”

Okay, sure, but the video, packed with sexy symbolism like ripe Edenic apples, also focuses on singer Chuu's stalker-level crush on fellow Loona member Yves.

"The fact that I took a step towards you first / It lets me find myself that I didn’t even know," reads a translation of the Korean lyrics, which include a reference to "hidden secrets that only I knew."

"Heart Attack" is particularly notable because while homosexuality is legal in South Korea, it remains taboo. Facing widespread stigma, most queer South Koreans stay closeted, even to friends and family. Director Kim Jho Gwang-soo and actor-politician Hong Seok-cheon are two of the country's only out celebrities.

Last year a court ruled against the first same-sex couple suing for the right to marry. President Moon Jae-in has said he does not approve of homosexuality and would not endorse an inclusive anti-discrimination bill prohibiting hate speech and crimes against women, LGBT people, and those with disabilities.

However, an estimated 85,000 people flooded the streets of Seoul this past summer for Korea’s Pride parade, the largest in the event’s 17-year history.
