Zhang Xiyuan, who is not mainstream and sentimental, met Wang Kai'an, a netizen who was seven years older than her, when she was dating online, and they accidentally became brother and sister.
Zhang Xiyuan is a rose raised by Wang Kaian, so his shadow is naturally everywhere on his body.
"You're still crying when you have me as your partner. Why don't you just laugh?"
"You are important. Only when I am admitted to graduate school can I see you often."
"We will always be together"
"I can't see you, so I just want to see the places you have been to."
