The girl Hesi, who studies in the art department of a prestigious art school, has always had a crush on her shy yet talented classmate Mark. Meanwhile, Mark lives in the dorm with another classmate, Jamie. One day, Hesi accepts an invitation from Mark to his dorm, but just as they are beginning to undress, Jamie suddenly returns, and the three of them end up in a transcendent relationship that defies societal norms... After sleeping with both boys, Hesi feels ashamed but has an intuition that this might be a setup: the shy Mark serves as bait, while the cunning Jamie joins in to take advantage... However, as Hesi grows closer to them, she admires Mark's talent and Jamie's ambition, and the three begin to live together. What confuses her is that even though they often have sex together, Mark has never been intimate with her alone, instead preferring to watch her with Jamie, which causes her to question the nature of their relationship... Hesi's mother's birthday is approaching, and she wants Hesi to bring her boyfriend home for the celebration. This makes Hesi a bit troubled, but she ultimately decides to invite Mark and Jamie to join... Will Hesi's mother discover their unusual 'classmate love'? Can their peculiar 'bed love' continue? And what secrets lie between Mark and Jamie? A passionate and intense love intertwined with paint is about to unfold... The film is adapted from an erotic novel that won the Spanish Erotic Literature Award, depicting the complicated love life of three outstanding students in an art school who unexpectedly develop an inseparable desire for each other while pursuing their painting art together day and night.
