Not so bad, yet not too good too. Author can have harem ending than one side ending. Well, since author didn't make scene all girls tears because Kogarashi choose Yuna, so i guess its fine ending
Well Ishihara doesn't wrong at all. Since he's first boyfriend to her, she just want to keep him for her alone. You know, young love treats entire worlds as they own worlds.
Well, this something really interesting...
