Maybe Becuz Uchiha's are Immune to it. 
Boruto isn't attracted to Eida either , Sarada Got Uchiha bloodline and during war Kabuto used his cells to revive Sasuke , and he had Hashirsama cells. 
If Sarada Even have an inch of Both side of the gene , she can be considered an otsutsuki. 
Her being just Infatuated with boruto is shit writing. 
I don't want another naruto-Sakura parallel.
