It's extremely simple! Make him a nobody!
His older brother is the protagonist of the novel. As it is to be expected, an OP with a harem...
His twin sister is a powerful reincarnator, collecting all the cheat items around the world...
Even his wife is not only an incredible beauty, but also a hidden goddess...
What about the character himself?
Well...the author of this novel seems to have forgotten about him!
Talent? Superpowers? Attractive appearance... or maybe at least wealth? 
None of that!
