Kyungsoo's home life was happy and nurturing, so I expect him to push for the same for his family. I like that about him, and he can be a bridge between Chowon and Mom. Chowon picked a good guy.
The relationship may never mend, and that's Chowon's decision to forgive. Sitting in the car with Kyungsoo, the mom realizes the way she raised Chowon has come back to bite her in the ass big time. Whether I think the grandma deserves a chance or not, Yoo Bin misses out. I hope things get resolved.
