The whole "Summer diary" PV is just too sweet, for me to think of any other actual words, right now...
I could seriously watch ayu & shuya's kiss, over & over! lol! It was just too cute.
And speaking of cute, the "one year later" ending was lovely, as well.
Although, I kinda do wonder what they meant by the "to be continued"...either the rest is up to our imagination or maybe one day there'll be a continuation...guess we'll see.
"Summer diary", in full, is such a beautiful song for the summer, too. I love it!
