Changed narrative

Before Jinwoo met Guwon, the prologue, or Jinwoo’s memory in the prologue thinks it’s a thief ransacking the place. In this chapter, it’s his dad returning after getting water. And we now know Guwon has some idea about what happened to his dad.
Now, the questions are: why was Jinwoo’s dad holding that piece of wood looking like a whacking motion? Did the dad resort to stealing from Guwon if Guwon tracked him down to knock him out? How long was Jinwoo’s dad out for if Jinwoo changed positions (wall to floor)? What’s the true memory of the day he met Guwon?
I guess Jinwoo’s lost and jumbled memories are the reason for these plot gaps and the confusion.
