回复 'newarm' 的评论 : I am agree with you. 以純 even didn't think about 楊梅's feeling, and the hurt to her. Also she doesn't have right to make decision instead of 楊梅.
楊梅 adopted 歡歡, so 歡歡 supposed to call 楊梅 as Mom, and call 以純 as sister. Why call 以純 as Mom. It is strange to call a unmarried and 20 years old girl as Mom in China.
