From all the new I seen about Hajimari so far it appears falcom is fixing Lloyd's harem by canonizing Elie and they are applying a bandaid to Rean by making him have special dialogue based on her CS4 Partner.

Well not for Hajimari but I would still say Alisa is Rean's way out of harem. Its not out of personal bias that I say this but because of how their relationship has been treated through the entirety of Cold Steel. There is clear difference with Rean's relationship on Alisa compared to other girls, this Subreddit loves to act blind on it but not only does Alisa's bond events focus on their relationship instead of being self centered but they also hint at Rean liking Alisa through and through.

It looks impossible with how Cold Steel IV making every female you can bond with reveal their love to Rean but Im still keeping hope because Alisa's bonding events still remain special in the ways I mentioned before.<! I'll refrain from discussing how badly executed other bond events were though.
