This is flipping cute -- all of it!
Ch. 1-2 - *On the first one - "He's gotta be dead, or he could be Nishida..." I thought, and I was correct! (¬‿¬)
Ch. 3-4 - Man, Haru is dense as a brick. But the fact that Hinata (aka Hina) is scary looking and the fact that Haru looks like a "hamster" makes this interesting and gives off a cute and fluffy feeling.
Ch. 5 - *Awkwardly reads... "Uhm... Ehm... well, that was beautiful. I liked how Haruhiko proposed five years before Iori did." ┬──┬ ノ( ゜-゜ノ)
-- God's doing made this possible... Maybe... that is if god is watching... maybe Haruhiko went to a shrine and prayed. ╮( ̄▽ ̄)╭
