On this day, fans all over the world are celebrating Jimin’s 30th birthday in a lively atmosphere. The fandom has carried out numerous projects to commemorate this special day, such as decorating Seoul and Busan with banners, LED lights, or birthday-themed buses, as well as organizing charity projects and celebratory events like river cruises and fireworks shows.

Of course, on social media, Jimin has also become the center of every conversation. Hashtags related to Jimin and his birthday began trending on various platforms early on the 13th. The whole world is sending the “angel” of October the warmest wishes and the sweetest letters.

Not only that, but many past stories between Jimin and BTS members have also been recalled as part of the event. They include a handwritten letter that SUGA sent to Jimin on his birthday 11 years ago — which was also one year after BTS’s debut.

On Jimin’s birthday that year, SUGA uploaded two photos to the group’s official Twitter account with the caption: "Firing the first g*n is Min Suga #ChimChimHappyBday"

One of the two photos was a handwritten letter, and the other was a funny picture showing his mouth wide open. However, these two photos gave fans mixed emotions — truly “laughing and crying at the same time” if you read the letter carefully.

Specifically, in the handwritten letter, SUGA wrote to his younger brother: "Hi Jimin-ah, it’s Yoongi hyung. Jiminie who was a practice bug* since [our] trainee days. Please don’t practice on your birthday and just rest haha. Jiminie who is always working hard and growing. You’ve improved so much and I believe that you will continue to improve. If you continue to work this hard, there is no doubt that you will become a cooler singer Jimin. Thank you for always working hard and I love you –From. Suga Suga Min Suga hyung–"

These words have gone viral again after a decade, once more moving fans who cannot help but be touched by their adorable friendship. SUGA has always been known as someone who rarely shows his emotions, and this letter was one of the few occasions where he expressed his feelings. Therefore, the letter has become even more cherished by fans — and surely by Jimin as well.

Meanwhile, through every line and word in the letter, fans realized how much he cared about Jimin. He knew how hard his younger brother had practiced and how much effort he had put into his performances, yet he still “couldn’t bear” to see him work so hard even on his birthday.

It is noteworthy that back in 2014, BTS had not yet reached the level of fame they have today. Therefore, when SUGA said things like “working hard,” “you’ve improved so much,” “I believe,” “cooler singer,” “thank you,” and “I love you,” it felt like both recognition and a sweet comfort. Surely, at that time, when Jimin read those sincere words of praise and encouragement, he must have felt happy and deeply motivated.

And just as “Minstradamus” predicted, the 30-year-old Jimin has indeed become a “cooler singer” loved all over the world!

In recent years, SUGA no longer “publicly celebrates” Jimin’s birthday in that way, but fans believe that the quiet birthday messages filled with the same love and warmth are certainly still there:

- Why tf did I read this at 2 am,now I'm crying and мιѕѕιиg yoonmin even more

- Love and friendship from Hyung Suga to Jimin. Happy Birthday Jimin.

- handwritten letter for Jiminie by Suga hyung. this is so cute, he’s his sweetest hyung forever

- Suga telling Jimin ‘I believe in you’ back in 2014... my heart can’t handle this. He really meant every word

- This letter shows how genuine their bond is. Yoongi may not say much, but when he does, it’s pure love

- Reading this after a decade makes me tear up. Jimin really became the ‘cooler singer’ Yoongi believed he would

- Yoongi’s not the type to express feelings easily, so this handwritten letter feels even more precious now

- I can feel how proud Yoongi was of Jimin even back then. Their friendship is soмєтнing truly special
