similarities between naruhina and ichihime: both girls; hinata and orihime, deeply love the protagonist from the beginning, and desire to get stronger to protect them. the protagonist is unaware of their feelings but is a lot kinder/softer when around them, and shows care towards the girls in return.

similarities between narusaku and ichiruki: both girls are hotheaded and hit the protagonist, and both “couples” are friendzone couples: as both characters involved only see each other as friends (naruto no longer has feelings for sakura)

similarities between naruhina and ichiruki: hinata and rukia act as a “ray of light” towards the male protagonist and are always around when the main character is feeling down or in a hopeless situation, they always end up cheering them up somehow and they both believe in the main character.

similarities between narusaku and ichihime: both main characters deeply care about the two girls (however naruto no longer has a crush on sakura) and put their lives on the line to protect them. 

i ship naruhina and ichihime but to shove narusaku with ichiruki or ichihime is a sin.
