jin's narration: while talking to namjoon, i went home as fast as i can.

during that day and time, he told me he's going somewhere with his car.

he didn't told me where but isn't his actions suspicious enough?

he believed you within the time you told him..

your situation is literally unbelievable yet he managed to process all of it within minutes.
