Ugh, anything but an open ending. Pick one girl, pick all, pick none, pick someone entirely different, end with a murder mystery, with Kaijus or aliens invading Japan or time-travelling shenanigans, get suddenly cancelled before the end and never finish.
Open ending is the absolute worst possible option for a harem. It's the greatest cop-out an author can choose.
I’ve never seen a Manga where the “Secondary Girl” wins so hard. Literally I will disregard the initial premise entirely, I just want to see her succeed.
I have no idea what the author is playing at by having your story based around the rivalry of 3 childhood friends and the guy they like include a fourth, objectively better, option. I think they had him be obsessed with a V-tuber and wanted to have her be a character without considering the consequences
I'm ngl, glasses girl is the best suited for him.
She's his type, is technically the girl he loves, loves him for who he is, he appreciates her and doesn't have any prior misgivings about her past, plus they complete each other. Her restraint and shyness and his outgoingness and confidence
