The reason why a special investigation prosecutor from the same university likely asked

A special investigation prosecutor from the same university probably asked him,
"Is there a reason why you did it this way?"
To which he replied, "I did it this way to block it."
Then, suddenly, the senior prosecutor said, "Speaking as a senior from the same school, I honestly don't need any other students from this university. I only need you."
That is why Busan has remained quiet until now.
To be honest, even after they failed him in the interview and drove him to a mental breakdown, he endured it all and ensured nothing happened. Normally, if you try to endure something like that, you die. He made him endure the impossible.
