Narration

Is anybody else wondering about the lack of narration/inner thoughts this season?
When I read the chapter about Sangwoo's past I was excited because I was waiting for it for so long but I was also disappoinet because we didn't find out about Sangwoo's psychological development (Koogi was very vague about this).
In the first two seasons Bum and Seungbae were either the narrator of the chapter or their thoughts were presented to us. That's why we know how they think. Especially Bum's development wouldn't have been nearly as good/thrilling without it.
But Sangwoo? There's only been one scene in which Koogi showed us what Sangwoo thought and that was when they were at the police station.
Somehow I'm simultaneously worried and excited about this.
I'm worried because it could mean that Koogi tries to please everyone and therefor doesn't want to be too specific about his past, personality, thoughts etc .
But I'm also excited because it could mean that there's a reason why she doesn't want us to know what Sangwoo thinks and she will reveal it later.
