Iron Mans Little Brother( Dropped)

I got my inspiration from Batmans little brother. Of course I won't follow the path of OP MC. I will also try some things I never tried before such as Romance.( please give me options for romance partner) no this is not a reincarnation and op system like my other novels. ----------------------------------------------------------------------------------- What happens if Tony had a little brother to share his life experiences with. Someone who is as intelligent as him but without his personality.
