There is no actual nudity in the film. Though lead actress On-On "Candice" Yu strips down to her bra and underwear in a scene by a fire inside a wooden shed. The lead actor Alan Tang also takes off his shirt in the scene.
In the same scene, Alan Tang and Candice Yu then engage in a very long and intimate sexual scene. They tongue kiss continuously for more than two and a half minutes. Alan Tang's tongue almost never leaves Candice Yu's mouth during the kiss. In one scene, Candice Yu opens her mouth and Alan Tang exaggeratedly extends his tongue entirely inside her mouth to lick Candice Yu's tongue. The exchange of saliva can be clearly seen between the two.
Candice Yu also caresses Alan Tang's bare chest and Alan Tang touches and holds Candice Yu's breast from the side during the sexual scene. This scene, though without actual nudity, can be considered explicit especially given the fact that lead actress Candice Yu was only 17 years old at the time.
