No, the manhwa will have a different ending to the drama as that ending was drama original.
Even at the current point of the story in the manhwa we heavily diverged from the drama's plot.
I would say the manhwa is many times better in general, be it the beginning of the story and especially the later parts where the drama became disappointing.

Spoilers for the Reborn Rich drama ending
Jin Do-Jun's body dies in an assassination attempt by the cousin iirc (son of the first uncle), so Yoon Hyun-woo, his original self, wakes up in the hospital in his past life.
He loses all the progress he made as the chaebol and traces down a prosecutor (his girlfriend in the manhwa) to try to implicate the new owner of Soonyang/his killer with flimsy evidence he had from working in his past life, and does so in a trial in court.
It basically undermines the revenge plot for a message of repentance and a return to reality and destroys all the progress of Jin Do-Jun, completely kills the satisfaction that would come from his life as JDJ and leaves huge plot holes on how he ended up in a different body or why he didn't help his og family if it's not reincarnation like the novel/manhwa (in manhwa the og family never had a son, they have a daughter, so he never existed, while that's not the case in the drama I think)
But yeah, the manhwa and novel heavily diverge from this
Guys will the end be same as the kdrama?
Cause i would stay away from it then..
