I am glad that Aoi and Minazuki temporarily parted ways. After all, Aoi was way older than Minazuki, who was still just a high schooler (even if he was more mature than him, ironically). Moreover, Aoi was an absolute failure prior to body swap, no jobs no friends no proper education, nothing. Minazuki, too, was suffering from his depressing condition of not being able to recognise people, that is literally the reason he latched onto Aoi and subsequently fell for him. I'm happy that the Manga decided to take a healthy route and let both of them make progress in their own lives, mature and heal instead of rushingly jumping into their 'happy ending'.
As for Yume and Sakura, man, after everything Yume had put her through, she didn't really deserve to get away with everything she had done and have her happy ending of being forgiven and reconciliation with Sakura. I would've liked it more if Sakura gave her a taste of her own medicine for a while and ignored her, but technically, knowing Sakura's personality, that wouldn't be very possible. Sakura was too fixated on Yume to care about anything or anyone else, and she even preferred to get bullied and hurt by her than ignored by her. She went through a lot of pain and endured, swapped bodies with a man to regain the love of someone who constantly hurt her, did everything to be in Yume's world again. I don't suppose this Sakura would willingly ever hurt Yume and push her away, especially when Yume is the one taking the initiative to mend their relationship. So, it might've not been satisfying, but it's pretty bittersweet.
