Despite efforts of fans to get to know their idols even more, there are certain things only an old friend can tell you about them. An example of this is the circulating testimonies of Jisoo's friends who are telling us her story before joining BLACKPINK.

According to Allkpop, an old friend of Jisoo described her as a nice girl, stating that the BLACKPINK member turned even prettier after joining the popular girl group. "I went to the same middle school as [Jisoo], and she was pretty but became even prettier," Jisoo's friend wrote.

She continued, "Her older sister also looks like Han Hyo Joo. [Jisoo] was really nice!! When kids like these become successful, it feels great."

Another schoolmate shared something funny about Jisoo, revealing she has caught the BLACKPINK member sleeping during classes plenty of time. "We were in the same class. Not really close, but she was good-natured, nice, and pretty. She did fall asleep a lot in class though lol (I saw her drool often)," the netizen shared.

Another one shared Jisoo would initiate a talk with her during their first year in the middle school. Given all the testimonies from Jisoo's friends, it is safe to admit that the BLACKPINK member is kind and pretty even before joining the girl group.

Meanwhile, Jisoo and the rest of BLACKPINK reportedly have filmed an episode for "Running Man" on Nov. 28, Soompi reported. A source affiliated with YG Entertainment said the four-member girl group was scheduled to record the episode in Jeonju.

BLACKPINK's episode on "Running Man" will be aired next month. This will be their second variety show appearance after their guesting on "Weekly Idol" aired Nov. 16.
