"She will not love you, Sebastian Saenz. There is no love as great as a mother's love. You can't just throw your mother under the bus for a woman who wouldn't accept you!" Camilla felt that she was speaking to a wall because no matter how many times she tried to knock some sense into Sebastian's head, he kept on staring at Winter with a gaze filled with unbridled love.
She realized that her son was hopelessly in love with Winter, but it was still hard for her to accept because she had spent decades raising Sebastian to be a perfect son for her, so she could get what she deserved.
She intentionally isolated Sebastian from any meaningful relationship so he wouldn't dare to fight back.
Camilla didn't expect Sebastian would fall in love so deeply with Winter in less than a year.
