Best family drama ever! I love that there were only 5 members of their family and others were considered outsiders the most ❤️ since the beginning til the end feels like a roller coaster ride that makes me sob and smile in each episode. Some can't understand how can they love their sister if they treat each other as siblings. Well maybe since the beginning you can't see it in Ling Xiao's eyes. Since he was a child I can see how he looked at Jianjian. He appreciate her the most. She was the whole world for him. I never seen him treat Jianjian as his sister. But He Ziqiu truly love Jianjian as his sister. He just got confused because of the people around him keep on insisting that he loved her as a woman but infact he didn't. You can figure it out if you look into their eyes. He acted as her real brother since he was a kid. He accompanied Jianjian in every trouble. While Ling Xiao doesn't want Jianjian to be on it cause he cares for her the most. It's also understandable that Jianjian chose Ling Xiao over He Ziqiu cause since the 1st episode you can see how much she likes him. Tho she's still a kid back then and doesn't have gender awareness til she become a grown up woman you can see that she love to stick with Ling Xiao. She loves to cling on him. She holds his hands more than He Ziqiu. If you can notice their eyes more you won't get confused how romance showed up within their family.
