This is my 3rd re-read and I just realized it even more that Jiwoo is really naive and simple.
It's obvious in his little back story, with how he believes in spending "forever" with someone, but this chapter really showcases how immature he is in a relationship. Here it's heavily implied he met Chaeun Park and had a physical fight with him, which made him realize that Eunsung has someone who is THAT in love with him. That Eunsung is actually THAT desirable.
It made him scared and insecure, which is why he decided to hook up with the girl and make Eunsung jealous. But instead of Eunsung acting like a hurt maiden like he did in the past, he got angry instead, which clearly made Jiwoo worried, shown with the way he hesitated to tell Eunsung that he and the girl didn't sleep together.
He basically acts like a kid. Eunsung is way more emotionally mature than he is. Which is why he acts like a toxic teenage boyfriend even though they're already in their twenties.
