Both graduation and confession also not that bad. Just that the confession in the episode is abit too sudden for me, same goes to the heart transplant but I think it doest matter now.
still a lot of thing didnt explain though... well overall was a great anime 9/10 :').
Actually I do hope to see Yui and Hinata in afterlife, wish there is a special ova talk about all of the character afterlife
.
btw, are both Otonashi and Kanade become lover in afterlife since both of them wearing a similar necklace, or just coincidence?
