I have a feeling that he's gonna remember all those memories and falls in lovd with everyone thus making the harem end closer but then again persuading every one to accept it a different matter
Hmm Oboro's story is kinda meh. But I guess it's a fitting one, her arc is a little more serious because she is originally part of the Ryuuga clan. Her motive is having strong baby for the clan.
Imo, what negi did with Gotoubun made other authos to realize the true potential of different routes or harem ending.
Im pretty sure that all these "delusions" will gather into 1 single Kogarashi and all the times he fell in love with the different girls will merge as one, turning into a Kogarashi that loves all the girls in ROMANTIC way, coz we know that he likes all of'em but he's not sure if that's love or what love is.
