Welcome to Shangri-La, a haven of sensuality where male companions revel in the delights of same-sex intimacy. Apollo, a newcomer to the establishment, finds himself responsible for preparing the gentlemen for their patrons, despite his heterosexuality and lack of experience. Phi, a seasoned and popular worker at the brothel, takes on the role of mentoring Apollo, all while teasing him playfully. However, both are bound by the strict rules of the brothel: no climaxing, no intimate penetration, and definitely no room for developing romantic feelings amidst the pleasure.
