The unpleasant things between them started because of her mother. She said, in China, same sex relationship could not lead to happiness. Sounds cliche, right? How about Japan? Same. I think I will prefer Thailand than those countries.
I'm completely disheartened after chapter 3 or 4, if I'm not mistaken, because she changed her sexual orientation. I'm not interested in this story anymore.
If this manga doesn't have the good (yuri) ending, I will consider it as one of the worst (supposed to be) yuri manga I have ever read. But right now, it hasn't ended yet and I'm still waiting.
From bad to worse, it's like they move two step backwards and there's the invisible wall between them. With this situation, their relationship is now too difficult to be blossomed.
