Fang Jianhao met her first before he knew what love was.
When Fang Jianye met her, she was his sister
Fang Jianhao said to her: "What he can do for you, I can do the same, and what he can't give you, I can give you..."
Fang Jianye said to her: "My feelings for you are definitely not like a brother's feelings for his sister. You are not my sister. It's great..."
Love, family affection, family business... How do the two brothers choose?
