An Instagram user wrote an incredibly hurtful speech for Sulli's mom, blaming her for using Sulli!

The remark was about Sulli's mom's participation in MBC's Docuplex. In an episode based on Sulli called "Why did you find Sulli so problematic?" Sulli was always in contact with her parent, and her bond reportedly mirrored that of two of her closest friends, not mother and daughter type.

After Sulli hit maturity, she asked her friend what kind of responsible investment planning mothers usually do for their children. Her friend replied casually, "I'm not sure, but they will 'usually' take charge of their kids." (via Koreaboo)

Sulli then stated that her mother had handled her assets ever since her earliest times, and she will always be provided allowances. When asked about investments; however, her mother told her there was none. To complicate things, her mother had been asking SM Entertainment for advances on her salary and spending all that money.

The late idol acknowledged that she did not know what tomorrow holds for her in the entertainment world and that her mom's reckless actions affected her. Then the friend mocked Sulli's mom and older brother for either not having worked their respective careers.

As a top-tier K-pop star, Sulli experienced struggles. She continually found herself bogged down in scrutiny and scandal, while her two family members took a piece of her profits. While the friend accepted that her daughter was born and raised by Sulli's mom, she was furious at the manipulative conduct.

Sulli's friend brought up the fact that Sulli's mother demanded to be paid upfront by SM that the fateful point when Sulli's connection with her mother goes awry. The friend states that Sulli largely relies on her family members throughout times of distress, who were, in turn, obligated to provide wholehearted support.

Her friend admitted that she had occasions when she ignored or sought to distance herself apart from Sulli throughout her 15-year-old friendship. Though, she was unable to suppress her anger at Sulli's mother, who not only manipulated her throughout her existence but used her once again after her death.

Sulli's mother seems to have learned about the documentary from snapshots from everyone. When she announced the showing, Sulli's friend was in absolute disbelief. She concluded her posting with a request to leave Sulli alone and not use her clout image anymore.
