Yes she is the FL's biological daughter.
The FL had a psychotic/nervous break down that caused her to forget giving birth and large portion of her life because she was traumatised that her daughter was born sickly and was most likely to die. The MC blamed herself and the ML quilting her for "running away" didnt help.
The daughter is so precious.
She acts so cold and indifferent to everyone especially those who care about her and have proven themselves yet for the ML and her father the two deserve the cold treatment the most she easily waivers.
Her grandfather is dead. The aunt is not a blood relative (though still a relative and I don't mean to say blood relationships are everything/superior)
The only other blood relative is probably her brother who is technically her cousin.
Also a parent is different to grandparents/other relatives. People more likely to forgive their parents than other relatives for the same action. Or at least that's what I think.
There's also a matter of time and people. The grandfather made an effort that's why FL accepted her way earlier than her father. Unfortunately he died too soon. If he were still alive, I have no doubt FL would treat him kindly (maybe in a tsundere way or maybe normally but still kindly). Also FL was still adjusting to being loved and cared for when the gramps was still alive. She didn't know how to feel about it or how to react to it. On the other hand, now it's been years since FL experienced the love and care from others. She's more able to care about others since she's being cared for too.
I wish he didnt end up with the MC who used him and slept with his brother behind his back. And the shitty brother knew Yura liked Moa and that he was sleeping with her but exploited the crush MC had for him to make her leave Yura because he was "lonely" not even because he liked that the MC the same way his brother did.
MC is such a disgusting bitch to sleep with both brothers like she did and treated Yura like shit











She she is shacking up with another guy and exploiting his feelings for her meanwhile she has her son dumped in an orphanage - in the same town to "hide him". Absolutely pathetic weak FL completely spineless can do anything herself whether it be run her own business or raise her own child.
Scream it!!! (╯°Д °)╯╧╧
Totally weak
