Honestly, I like the character designs for the girls and all... but... you know this entire harem situation is forced with the unnecessary hiding of the relationship... there better be real consequences, like the MC building a harem or a flat chest loli girl killing herself just to make the main girl realize how stupid she was (extreme, yes... but I'm just that convinced she won't suffer real consequences; though I prefer the harem).
@Jugglusjuggler Not true; it actually happens quite a lot... the fact that the childhood friend loses is actually a myth. This chapter pointed out that the childhood friend winning is also a very common trope. The real truth is, the one that will win 90+% of the time is the main girl... all that matters is if the main girl is the childhood friend or not.
The real reason we have childhood friends lose so often is that authors add them to give the series an extra love interest, but have less development for the character, because, hey, they're childhood friends, they are already developed...
