七码滚雪球

简介：When the two of them are together, they usually don't call each other sisters. They call each other by their first names and go straight to each other. The main reason is that the younger sister Ling'er feels that her elder sister's personality is not worthy of being an elder sister. She can't be her younger sister just because she was born a minute later. Not convinced. So he calls Yu'er by his name every time and always bullies Yu'er.
