Dilan 1991

Milea, now in a relationship with Dilan, faces problems. He is involved in an aggressive motorbike gang of his school, engaging in fights every other day. This eventually leads him to get expelled from the school. She still tries to understand him and does not let the relationship get affected. Meanwhile, her cousin Yugo comes home from Belgium, and started acting incestuous towards Milea, which makes her uncomfortable.

One night, she sees Dilan planning an attack late at night, threatening him that she will break up if he does not mend his ways. Seeing Yugo as a foreign man in the car, Dilan does not see this as a threat and thus continues, to the point where he is caught for being involved in an attack using his father's pistol and ends up going to jail. One day, Milea's parents advise her to guide Yugo around Bandung. In a cinema, Yugo tries to kiss Milea; she runs away from the mall in rage and asks Yugo not to see her again. In an apology meeting, Milea brings Dilan with her and uses him to scare off Yugo.

Milea learns that Dilan is involved in another attack; this time he is kicked out by his mom and thus refuges at the gang leader's house, along with a lot of other members. Milea slaps him, tired of his involvement in problems, and declares breakup. Dilan insists on taking her home and she relents after much compelling. She is protected by Dilan's mother who lectures him at a stadium. He walks away, leaving Milea crying under his mother's shoulders. The film then fast-forwards in time, showing Milea graduating college and her family moving out of their home.

In 1995 in Jakarta, when they're adults, Milea, now married to her college friend Herdi, sees Dilan at an office building that the three of them work at. Dilan tells her that he is leaving for Surabaya that night. Milea instantly try to catch the train he is leaving from. She sees someone that looks like Dilan but is not. Knowing that the train left, she sits on the bench and cries. In 2018 at Milea's apartment, she writes the last few sentences of her memoir, a direct copy of Pidi Baiq's novel which the film is based on.
