Time Gap is a five page, complete comic (I made it for a comic seminar i attended). I'll write the summary but not the ending so you check it up! :)
It is a story about Kazuya a high school student, who has the same dream everyday. He dreams about himself six years old playing with a girl whose face he can never see; but suddenly the sky becomes dark and the girl starts fading away. No matter how much he runs after her, he can never reach her.
What he doesn't remember is that that girl actually existed. They were friends, but she had the ability to foresee the future. Her brother was dedicated to protect her after their parents were killed (by people who wanted to use her ability) so on his attempt to protect Izumi (the girl), he pushed Kazuya of a cliff. Blaming herself for Kazuya's injury, Izumi erased his memories of her.
In the present Izumi doesn't talk, so she doesn't 'cause trouble for anyone. A series of events though, will cause Kazuya to find his memory and they start hanging out together again; but Satori (her brother) isn't pleased about it.
If you want to learn how the story ends just go ahead and read it! :)
It is a manga so you have to read it from your right to your left.
