As a native Korean speaker who learned programming in English the code looks very easy to read.

The downside is understanding logic feels harder because - the order of Korean is diff from English - e.g. "동안" (while) hard to reason about as "동안" comes after the condition in Korean linguistics and comes before in English.

So my only suggestion is to go diff direction from normal writing flow as shown below for readability

- from: 동안 n < 5 - to : n < 5 동안
