I read the novel raws and it's just classic misunderstandings.
Both like each other but think the other is indifferent to the other. They start a physical relationship with Jeongyun thinking Chaeheon only wants him as a fuck buddy. He also thinks another girl is dating Chaeheon (spoiler alert, it's his cousin).
Jeongyun goes on a trip and loses his phone while things are still ambiguous between them. He comes back, Chaeheon is upset and basically tells him to stop playing around with him. They confirm their mutual feelings and become a couple. The end.
