A Tree Without Roots - Chapter 68

So Tae-kyung could forget the fact that his mother murdered someone cuz she had a cancer ( which btw she has aready recovered from and living freely and happily), but he won’t believe the fact that Hee-seo did not murder anyone?? I get the fact that Hee-seo is very overbearing, but I think that his attitude which changed at some point in the story is also Tae-kyung’s fault.
I also get the fact that nobody would want their parent to go to prison, but the fact that Hee-seo has continously been tormented starting throughout his childhood and did not have anyone to lean on to the point of finding about the truth of evrything and neither getting justice for it is really sad.
But then again, Tae-kyung is probably the only person who can understand Hee-seo in the end so I hope things turn out well soon.
