father of Rieko Saibara
The manga artist says that on the day she was forced to leave high school, her second father waited in kimono for her at home and hugged her. He didn't say "it's an embarrassing thing," but instead he accepted her existence unconditionally as if to slobber over her. From "Muddy Quotations That Can Be Used If Washed." This experience is important. she doesn't need to deny herself, she must think her father's saying is too much and she will never overestimate herself since then.
