In December 2018, 19-year-old architecture student Karl Frederik Almasen moves into his uncle Santi's former apartment as his parents want him to be independent. He becomes a film-themed freelance writer due to his cinephilia, but struggles to attract clients. One day, his neighbor, Jose Vladimir "Vlad" Austria, enters his apartment to hide from his sister Judit; assuming he is a burglar, Karl checks his pants, but Judit opens the door and assumes they are performing fellatio. Vlad then forges his relationship with Karl, stating he will not visit his mother until Judit accepts him. To make him feel comfortable, Vlad promises to Karl that he will help with his rent.

Karl is uncomfortable with the forge; Vlad tells him to think of it as a gay-for-pay situation but is kicked out nonetheless. While at his apartment all alone, Karl begins falling in love towards Vlad. The next morning, Karl gives him shelter as he has no place to stay now. It is revealed that Karl is a closeted homosexual, expressing his sexuality through euphemisms, while Vlad is an open one. Karl is hired by a film review website to write search engine optimizations, and Vlad reveals he is in film school. Karl then asks him to be his housemate, saying he wants to transfer to film school as he aspires to do filmmaking. Vlad accepts.

Karl scolds Vlad for not cleaning the mess he made to the apartment, which turns into a quarrel. Judit apologizes, explaining that Vlad is not used to sharing rooms with other people. Karl then reassures that Vlad also cooks delicious breakfast, and that his passion for film is inspiring. Vlad also explains that he was moody due to rejection from a Japanese film laboratory. Karl accepts, and also apologizes for his attitude.

As Christmas nears, the Christian Karl decorates his apartment accordingly, but Vlad, whose birthday coincides with Christmas, reveals he does not believe in God though is comfortable with the decoration. While on a call with his friend, it is revealed that Vlad has feelings for Karl. While Karl spends Christmas at his parents' home, Vlad misses him immensely that he dances, imagining him and Karl kissing. The next day, Vlad awakens to the decor theme changed to a birthday one, with Karl back.

One day, a district-wide brownout commences. Karl and Vlad decide to spend the night together with neighbor Anna, also Vlad's friend since a teenager. They exploit the dark night by telling urban legends, then move to the gazebo to vent to each other; they learn that they were in Catholic schools. Karl and Vlad, feeling electric, dances and is about to kiss, when the power is back on. The closeted Karl rushes back to his apartment due to anxiety.

When Judit comes and reveals that Vlad's mother reserved a dinner with Karl and asked for his parents' address in an effort to know him more, Karl reveals the forge in a fit of anxiety. Furious, she takes Vlad away. Karl reveals to his parents he never has passion to architecture, a major his parents always wanted him to go to, infuriating them. After Vlad explains everything to her, Judit apologizes, additionally addressing her past homophobia. Karl pleads Vlad to come back as he misses him; Judit allows. While waiting for Vlad, Karl dances femininely, expressing his sexuality. Amid the dance, Vlad enters and joins Karl, who then kisses him. They spend the next day recounting their childhood and cuddling in bed.

Karl, Vlad, Anna, Judit, and Santi have a dinner at Karl's apartment. Santi talks to Vlad, while Judit can talk to Karl, on whether they are actually in love. Karl, overwhelmed with the discussion, goes to the gazebo and sees a screen playing a home movie of Karl, marking their one-month anniversary. Vlad approaches and they kiss, but Karl sees Anna, Judit, and Santi looking at them. Karl panics on the latter, but Vlad assures him that his uncle sensed his sexuality for a long time. Vlad is hurt on Karl for being in denial when he asks him to say that he is gay, equating his denial to criminals when interrogated.

Vlad moves out of the apartment. Santi assures Karl that it takes time to be an open gay person. The next night, Vlad walks in the apartment drunk. He went to a bar due to stress, where he learned that his ex broke up with him for another man. When Vlad apologizes for forcing him to be open, Karl says "I'm gay", and Vlad congratulates him. Karl, however, says he is still not ready to say that in public; Vlad says he can take his time. While cuddling in bed, Karl says he wants to be with him forever. The next day, Anna suggests that he come to terms with his sexuality and spend his time to make the most out of it.
