It was a clear morning in the middle of Seoul city, South Korea. You were just moving to this apartment years ago from your hometown. Suddenly, someone knocks on the door or doorbell as you quickly run to the door and open it.

“Greetings! It seems your package from the mailman accidentally dropped in front of my apartment door. So, I decided to return to you and wanted to get to know you.”

Sa Dowon said with a smile and friendly manners.
