No need to comment on how Min Heejin conducted the interview since everyone is talking about it.
However, while it made an interesting show, in longer run she has shown her weaknesses and also shown that she does break down, and would make irrational choices to save her face. She also showed that she will reveal private conversations if pushed, making anyone talking to her will be extra careful while dealing with her.
Lee Jieun , meanwhile, was called by Yoo Inna as a very old person. Lee Jieun is a very calculating person.
After the revelation of her most famous photograph, she showed up at Inkigayo the next sunday as if nothing had happened. At that time the MC of Inkigayo was IU , and ... Lee Jongsuk.
Lee Jieun, who was now producing her album by the time the Zeze controversy hit, did not really explain anything about it and waited until the brouhaha died down, and she chose to spend 2016 doing the ill fated Moon Lovers. So by the time Through the Night came, no one was remembering the Zeze thing.
The correct move for Min Heejin would have been reconciliation. It would have been more beneficial for her to try to make up with Bang, who is much more powerful than her, and bide more time although Bang would have added more restrictions on her.
Instead she simply exploded. While that will make her the talk of the town for a few days, business is business and the court does not give a crap about what she has said; it only uses hard evidences.
There is a reason that Lee Jieun, not Min Heejin, got to become the nemesis of BTS. Lee Jieun, to this day, has not lost her restraint and always has managed to crush her rivals without saying anything. Perhaps that might be why Yoon Mirae, who had seen Lee Jieun before, had restrained Kim Hyungseo to not to provoke Lee Jieun too much?o
Something like that happened to Lee Jieun when she had owned Edam Entertainment. Kakao apparently had the take back option on her 60% stake of Edam Entertainment, and it took back 12.5% of the shares, returning to the majority owner in April 2022, because apparently it was afraid that Lee Jieun would sell her shares to someone else so it had to make sure it owned the majority share, but Lee Jieun has said nothing about that to this day. It was rumored that Lee Jieun would get Kakao Entertainment shares when the latter became public, but that has not happened to this day.
Hybe is powerful, and there are a gazillion ways Bang can use to bury Min Heejin. Since Min decided to reveal dirt on Bang and his lieutenant, Bang would also have weapons in his arsenal and since his ego was struck, he won't let this go away easily.
I have to conclude that Lee Jieun is a much better businessperson than Min Heejin, which is why Lee Jieun is ranked on the same tier with BTS.
