@saphirekosmos Well, lets be honest, there are a few times where they have won. Few, but they exist. Lets give them at least that much LOL
Like when they are the FMC or when the girl the MC is in love decides to return to the future from where she originally came...
@Tearsax I honestly can't think of any I have read/watched where the childhood friend alone wins. I have seem a few harem endings involving the childhood friend, but never one where she was main girl. Would love a few examples if you have them. Throw them in a spoiler tag and I don't think anyone would complain about you posting them.
My absolute favorite type, childhood friends romance, but it has no chance at all
From chap 1 it's obvious that the end girl is Hanako, building a harem is useless IMO
