Brother's Keeper

The Group Loves the Sick, Weak and Gentle Brother

I want to read a book similar to "The Villain Brother Was Pampered to Heaven After Rebirth". It's the kind of anti-abuse story about rich parents who neglect the oldest child (who wants a eldest brother!) After having younger children. The eldest brother is busy working in the company and his physical fitness declines! No heroine! Group favorite Xiang
