"If it's been 10 years, we're family" SF9, a profile talk piercing through each other's strengths and weaknesses

The group SF9 strengthened their bond by creating new profiles for each other to celebrate their 10th anniversary since debut. In a video released on October 5, 2026, the members guessed each other through cherished items they brought, and shared changes over the past 10 years without reservation based on hand-drawn portraits and written profiles.

A 10th-year 'exposure war' started with cherished items and portraits

The content began by opening with a game of guessing the cherished items brought by the members. As unidentified objects such as hair ties, gym equipment, and English-related items appeared, the members showed their intimacy, saying, "Since we've known each other for 10 years, we can guess just by looking at the items." In particular, an atmosphere of naturally sharing each other's daily lives was formed as items with specific members' names or items frequently used at the airport appeared.

In the subsequent portrait drawing and profile writing stages, the members' unrestrained expressions continued. The member who drew HWI YOUNG's portrait drew it reflecting HWI YOUNG's characteristics, and the members drew laughter by mentioning each other's changes in appearance or characteristics while looking at the completed drawings. In this process, the members showed the bond accumulated over 10 years by exchanging jokes using each other's hairstyles or physical characteristics as material. In particular, the candid appearance among the members caught attention, such as describing the number of hairs or mentioning skin elasticity while writing IN SEONG's profile.

"Became flexible, vocals improved"... Changes from 10 years ago

Through the written profiles, the members specifically mentioned things that have changed compared to 10 years ago. DA WON stated, "The thing that has changed most compared to 10 years ago is flexibility," revealing changed physical characteristics through stretching, etc. JAE YOON even received recognition from the members by including the content "dance skills have improved recently" in his profile. Regarding HWI YOUNG, members' comments followed, such as "he has a charm that attracts people just by holding a camera up to him" and "unlike 10 years ago, his vocal skills have improved a lot."

On the other hand, they picked 'hairstyle' or 'stamina' as things that have not changed for 10 years, having a pleasant conversation about the members' appearances that remain the same even as time passes. YOUNGBIN mentioned that his appearance has developed compared to 10 years ago and he has become youthful, while DA WON expressed with a double meaning by picking stamina as something that has not changed for 10 years.

'SF9-style' profiles defined by personality and habits

The members recorded in detail each other's MBTI and characteristics according to mood changes. DA WON mentioned that although he is an I (introverted type), an E (extroverted type) personality appears depending on the situation, and YOUNGBIN included in his profile the characteristic of talking a lot or playing pranks next to someone when he is in a good mood, and the youngest-like side of showing an attitude of wanting attention when he is sulking. It was revealed through the members' records that JAE YOON has the characteristic of holding onto someone to listen to him for more than two hours when he is sulking, and CHANI shows a one-dimensional reaction of starting to talk when he is in a good mood and trying to sleep with eyes closed when he is sulking.

Jae-hun showed a serious side by writing the motto 'I hope I live by putting in a lot of effort' in his profile. Through the process of comparing each other's profiles and checking how much they match their actual personalities, the members completed the 'family-like' chemistry that only a 10-year group can show.
