K-pop group Girls' Generation made a comeback on August 4 with their sixth studio album 'Holiday Night,' after being on hiatus for most of 2016. The group also revealed in a recent interview, their thoughts on which members among them have changed the most, through the years.

As noted by website Soompi, on August 10, Girls' Generation appeared as guests on KBS2's talk show 'Happy Together' and they named the members whose personalities they thought, have changed the most since they began their journey with the girl group.

Girls' Generation's Yuri said and the others agreed, that Seohyun had changed the most out of all. Yuri said, "[When we first debuted,] Seohyun would answer our questions very quietly and in a timid manner. There was a time when she didn't speak for a month and we thought she was sick," and added, "But now Seohyun has changed a lot. She's become a very bold 'maknae' (youngest in a group)."

Sooyoung on the other hand said that it was Yuri herself who had changed the most. "Yuri used to have a playful image. I thought that lately her image had become more of a sexy and luxurious one; however, seeing her today, I see that her playful side is very much still there," she said, making everyone laugh.

Meanwhile, Soompi also notes that the Girls' Generation members will appear in the upcoming 'Running Man' episode that will air on August 13. They will be seen participating in a game which will have them answering all the questions they receive, in just five seconds.

The filming of the 'Running Man' episode has already been done. Girls' Generation's YoonA was asked, "How many boyfriends have you had?" While those who want to know the answer will have to watch the said broadcast, it was also noted that YoonA will form a love line with Lee Kwang-soo in the said episode.

Lee Kwang-soo is often seen falling for beautiful female guests on the show to the point that it has become a running joke among the variety show members. YoonA will be no exception in this case, as Kwang-soo was heard telling the 27 year-old singer and actress, "I only have you" and "I will protect you until the end." He also asked her, "Can't I like you?" Hopefully, he'll find true love sometime, in the near future.

The next episode of 'Running Man' with Girls' Generation members will air on August 13 at 4:50 p.m. KST on SBS.
