The ending is kinda meh. I dont mind the open ending with "ongoing journey". But it just don't work here, for me. Like, It actually the same thing when Oono's first leave and it work back then.
First, get rip off inner dialog, all of them. This is not a shoujo. Second, Author shouldn't give him another chicken out time again just to boot a climax which is lame, the depression of losing the game is rather unnecessary as well, Especially after he realize his feeling, this is just drag out, and they are too long. Just go there, give her the ring, and then we got the ending, they promise and shit.
sometime, less is more.
Like, we got the whole "everything is possible with love " and he didn't actually fly the scooter up there and pierced through the plane or anything ? Disappointed !
