Jin is known as an idol with a golden personality as he is always polite and sincere to those around him. Even if he hasn't become a world-class star like he is now, he still shows his good personality.

A post on an online community forum gained attention as the story of BTS Jin's college days was repeated by fans. This story was told by a user whose father was Jin's professor at the university.

It is known that Jin debuted as BTS while still a college student at Konkuk University. Many students who studied with Jin revealed that he was a very polite student who always asked many questions about the subject or the test.

Because of becoming an idol, Jin's schedule of activities with BTS sometimes coincides with his school schedule. So Jin is always texting the professor about his schedule or why he has to leave school.

Jin also always texted the professor first asking when it would be a good time to call before he actually made the physical call, revealing his polite manners.

In regards to group projects, Jin requested if he could do an alternative project instead so that he wouldn’t be a burden to the other members of the group due to his busy schedule.

The poster also felt that Jin was very sociable because he was always good at reacting to the professor’s stories and also prepared signed albums for him with a genuine and thoughtful message inside.

He would also miss at least one class every week due to his busy schedule, but he never missed sending a text to let him know that he couldn’t make it and apologized for his absence. The professor revealed that he was the most shocked and happy at his attitude of always trying to make it to class when he could.

The professor also admitted that one of Jin’s reasons for missing class was truly world-class status and will always be a text he will remember. He texted the professor that: "Hello professor this is BTS’s Jin. I am currently in Hong Kong to perform at the Mnet MAMA and will not be able to make it to class. I am very sorry."

The poster remembers even seeing Jin in their father’s class one time and saw how proud their father was of having Jin in his class. Although he didn’t show it much, he truly did enjoy having Jin in his class and was happy to see him always trying hard.

The poster thanked Jin for gifting his father a special memory during his time there. Of course, his dad ever teached megastar and Worldwide handsome Jin!
