So the basic premise of the story is fl lives a mediocre life. She's married to a man that tolerates but doesn't hate her, she's treated poorly by her mother in law as well as other nobles and she lives her entire life in the shadows. The only thing that brings her genuine joy is her daughter. 

During one of there many conversations the daughter tells the fl that if she ever gets the chance to relive her life she should live it the way she wants to freely, with no guilt, and not worry about her not being born. The daughter is very EXPLICIT about this wish. It's said multiple times. If the fl gets the chance to live her life again she should live as she wants and marry for love and happiness.

our fl gets a redo of her life, and immediately starts living as she wants. She brings herself to finally make a connection with the ml, a person she liked in her first life, and asks him to be her partner at a ball. They hang out and get to know each other. Eventually the fl and ml fall hard for each other.

Now this is where the trouble starts, because of the fl.

the fl still misses her daughter and can't cope/ adjust to life without her. Even though the fl is in love with the ml she misses her past daughter more. So even though the fl and ml love each other and the daughter said DONT WORRY ABOUT ME BEING BORN AND LIFE A HAPPY LIFE the fl tries to cut off the ml with no explanation and goes back to living her old life so that her daughter can be born. She gets in contact with her past husband ,so that her daughter can be born again, even though it's clear he loves someone else.

The biggest downfall of this comic is the fl. she's sabotaging her own life, hurting many in the process and is too stubborn. I understand that she misses her child but how many times did she have to say LIFE FOR HAPPINESS?!

Imagine being given the chance to relive your life and you choose to fück it up again.
