He likes Lu Nianxi and never hides it.
The two parents have a good relationship, Tang Ruoqing and Su Nanxing meet almost two to three times a week.
They both work in the same hospital, and aside from meeting at work, the two families gather at least once a week.
This greatly facilitates Ying Boyan and Lu Nianxi meeting up.
Moreover, during winter and summer vacations, the kids almost always do activities together.
As soon as it's vacation time, Tang Ruoqing just sends Ying Boyan over, and he stays and eats at the Lu Family.
Ying Luoyu sometimes goes to the lab and doesn't come home for several days in a row.
Tang Ruoqing's surgeries are also fully scheduled.
She trusts Su Nanxing to take care of the kids.
So, once the holidays come, she becomes hands-off.
Lu Nianxi has always had a good relationship with this younger brother. They've played together since childhood, so she has no objections to Ying Boyan staying at her home.
