both are peak shounen. 1st one is harem but don't be deterred by that, it's really well-done

yall I need a manga/hwa/hua with an mc that has a really deep platonic relationship with someone. like to the point where they’re soulmates and cant live without each other, but NOT romantic or at least not an explicit one.. (⊙…⊙ ) can be any plot, horror/action/fantasy etc..
