Fanon
Majority of the Fandom Dislike this due to Incestuous vibes it gives since yuka and Satoshi are canonical Siblings

However there is a fair amount of Shippers for this pairing,Especially with the shipping fuel from CP Musume having Satoshi reciprocate Yuka's feelings along with believing Yuka's feelings is the most Pure compared to the other girls in Satoshi's Harem https://corpsepartyconfessions.tumblr.com/post/49972542599/incest-is-creepy-but-i-think-yukas-the-only-one/amp
