Akihiko-'s manga / #mature(1)

I will never understand why the author need to kill katou. They deserved better. First watched the anime so i really love the anime version and had high expectations in the manga thinking "the ending must be so good, loving each other 'til they're so old they can barely walk" but nooo, they gave us a dead katou. Loved this for years but absolutely devastated at the ending, can't imagine for those ppl who has been loving this since it first came out :<
