Conflict With Seniors
The two figures that Wijaya currently sees on the 3rd floor, are two figures of people he knows.
Or rather they are people who will be very involved with him in the future.
And that person is Freya, a female friend who is in the same class as him, and also his senior who is in the Saung organization named Rangga.
The story between Freya and Rangga is actually a classic love story, between seniors and juniors on campus.
It's just that what Wijaya doesn't like is the fact that Rangga is a senior who is very playboy and likes to play with the women around him.
And of course this is very much disliked by Wijaya, because he clearly remembers that when he later joined there were several women who were known to have been dated by Rangga's seniors.
All of which then ended in breaking up and leaving a conflict between them.
