Was Lee Jae-myung trying to return to a chairman-centered system?

Just like during Chairman Kim Dae-jung's era..
Did he want to turn it into "Lee Jae-myung's Democratic Party" rather than the Democratic Party of Lee Jae-myung?
While it might be impossible in formal terms, wasn't he trying to place the government and the party under his own influence?
Was he perhaps wanting to flaunt his power to create a conservative and vertical organizational culture?
I'm just writing a delusional novel here.
If I'm wrong, so be it. It's a relief if I'm wrong.
