Here's some examples of those creative storytelling scenes:
- Jingi explains their job to Myeong-il (both through what's said in the newspaper and by explaining): [Ch.13 p.3]

- Jingi has an abstract nightmare (presumably about visiting his mom in jail): [Ch.17 p.22]

- Jingi explaining to Heonjae about Myeong-il's gambling addiction. The pen he throws visually becomes a severed finger on top of playing cards implying that Myeong-il is a hopeless gambler that won't stop even if his fingers are cut, which is also referencing that time when Myeong-il did attempt to cut off his own fingers due to a major loss from gambling in a flashback once but even now he hasn't stopped or learned his lesson: [Ch.27 p.6]

- The chapter starts with a vague flashback just filled with colors as it was through the perspective of the blind Noona. (something about pictures? I assume that's what in the letters Jingi refuses to open or show Myeong-il): [Ch.34 p.2-8]
- Myeongyoo (Myeong-il's sister) having an anxiety attack as she's scratching herself from fear, though it feels like being scratched all over, then thinking the voice that spoke next was Myeong-il because she wished he was there to protect them :'(( : [Ch.34 p.22]

- Jingi explaining why Heonjae and Myeong-il together won't work. Myeong-il is a puzzle that Heonjae won't be able to solve (bc Heonjae generally can't understand people much, and Myeong-il is also f-ed up in his own way) (also the puzzle is made of the stamps Myeong-il won, not sure what that means.): [Ch.35 p.19]
