I 'm feeling guilty now, how greedy and shameless of me to steal those beautiful artworks from their creators for something like this, I wish I didn't have to be this way. From left to right and top to bottom, the first one with such dreamy style is a beautiful illustration by Haruhiko Mikimoto, the second is an amazing artwork by Kosagi Midori (http://www.pixiv.net/member.php?id=7738391), the third with such deep feelings in it is an creation of Yokoya (http://www.pixiv.net/member.php?id=13854) and the last one, the girl with that sadness in her red eyes, the girl who always keep her face emotionless while still giving so much emotions to us, of course is Enma Ai from Jigoku Shoujo.

And I do miss those days too, will never forget it, the time of an early summer, raining, the haze air, red petals all over the schoolyard, the last moment spending time with my friends, doing stupid things inside the schoolgate, mocking each other, smiling and laughing too much, my first love, didn't get enough courage to confess, the time when the child inside me still didn't know what I was losing, still believe in something like an unchanged future or at least I was able to try so, doing useless things just because I want to without having to consider if it was a wasting of my lifetime, some of the teachers were pretty fun too. Thinking about the happy past, which isn't there anymore and will never be found again in the future, and how weird it is, a mixed feeling between happiness and sadness like this always give me a peaceful feeling, like "everything is fine, it was full". Well, who knows the last day of young time. In short, I wouldn't mind to go back too.
