Comment by TREXSA on At the End of the Road - Chapter 45

So it turns out that the Blonde psycho woman's child was the blonde ml. The ml had a Half brother whose real name was Min Siwoon. The half brother ( the brunette ) was already bedridden. The brunette haired lady is the mother of the mother of bedridden boy. So they adopted Min Woojin(ml) to take over the company. They got rid of ML's psycho mom.
ML's real name is Woojin, he was just framed as Siwoon just for heir issues.

(That's what my brain figured out)
this manhwa is harder than those UPSC exams questions.
