Jimin is one of the most popular idols in K-pop. The “Filter” singer has captured a lot of hearts, including non-K-pop fans, with his good looks, talent, and charm.

ARMYs also love the fact that Jimin has an amazing personality. To show the BTS star how much they appreciate him, fans trended four keywords on Twitter on the very first day of his birth month.

Jimin is turning 25 years old (26 in Korea) on Oct.13. ARMYs all around the globe have been organizing projects to celebrate his birthday, and the very first one is trending #HelloJimtober along with three other keywords on Twitter in Korea.

Even though the month just began, there are already over 120 birthday projects dedicated to Jimin. ARMYs have set Jimin-theme bus, donations on particular causes, road banner, large scale advertisements, and more for the BTS star’s special day. The fandom is known for organizing both simple and extravagant events for the members for years.

Meanwhile, Jimin’s popularity is not limited to him being a part of the biggest boy band on the planet right now. People are instantly drawn to the BTS singer with or without RM, Jin, Suga, J-Hope, V, and Jungkook.

As if his good looks and singing and dancing skills are not enough, Jimin is also one of the most kind-hearted and sweetest idols out there. The other BTS members and ARMYs know the “Filter” singer as this kind of person, and his old pal revealed that he had always been like this.

Jimin’s friend shares what he was really like in high school. Kim Daehoon uploaded a Q&A on social media, and he noted that many of the inquiries were about the BTS star.

Just like Jimin, Kim Daehoon is also from Busan and went to Seoul to study. He happened to be sitting next to the BTS star when he attended an arts high school during their teenage years. The pair struck up a friendship, and their bond lasted to this day.

At the time, Jimin was a trainee. But, even though he has already reached superstardom status, he still keeps in touch with Kim Daehoon and meets up with him occasionally.

“I realized that not everyone will change after they become successful, people who are kind-hearted will still be very kind,” Kim Daehoon said.

BTS members are known for their humility despite their success. While most celebrities would let fame and fortune go up to their heads, the group has never forgotten where they came from and have always remained grateful to their family, friends, and fans.
