Interesting Concepts and/or No Romance

I have always wanted to read a series about a genuine relationship between a mom and her daughter. I want to see the struggles and happiness as a female for another female, and how the mom, who plays the role of the only parent, would want to shape the perspective of her child who will in turn be another woman. This is a beautiful manhwa that shakes me to the core and it reminds me to appreciate the remaining time we have together.
