It’s not that Kade was brother hopping but that he had a subconscious attraction to Akita’s brother because of their similarities. Kade’s first love was Akita as a kid but obviously over time he forgot abt it and then sees someone who aligns with his type (aka his past crush) and falls for him. It’s only after Kade confesses to Akita that he remembers that the kid he first fell for was actually Akita all along. So it’s more like he fell for akiras brother because of the similarity to his first love but only because his forgotten first love was Akita all alongヾ(❀╹◡╹)ノ~

making kaede actually like akira first due to some childhood thing makes it worse because what do you mean you liked akira when u were kids, had a crush on akira's brother after akira basically rejected you , starts acting like a bitch to akira.k.a. the are you really his brother (which makoto did not like at all and one of the reasons he remains iffy about kaede), then fall for akira again.
they should've just established that kaede's like for makoto was superficial because makoto was kind to him once rather than make this a 'oh i actually liked you before i liked your brother then i started liking you again because i had no chance with your brother and you were there to comfort me'.
kaede also has the reoccuring theme of kissing akira without his consent (when akira was asleep in the infirmary), being pushy with akira the same way some of ya'll dislike hina for, being super possessive over akira like he wasn't into akira's brother just last week, and then even pushing akira down to kiss him (just like hiragi did even though hiragi was worse because thats a grown man assaulting a teen essentially).
despite this, im looking forward to how kaede's route goes since i've seen some people mentioning that the manga isn't exactly a one to one copy of the novel?
also; how many routes are there going to be? we got two now (natsuhi's and kaede's) then some say there's gonna be a route fot hiragi and then the prez? someone confirmed that there's a shirousa route but no route for her younger brother. a hina route probably. what about the 'teacher' a.k.a hina's fujoshi friend? seems interesting.
actually really want a haruki route just for funsies to see how that goes because shirousa mentioned that he's a legit capture target for the akira in the game's season 2 and we saw a sneak peak of HaruAki and then Makoto with the Prez if akira goes through the looting route.
ngl, knowing that makoto is also a brocon makes me want a route with him because i know that akira the brocon would go crazy lmfao.
