When I Reincarnated Together with Her

I'm a novice writer, but I'll keep trying to improve myself to be better :)

Warning : English is not my language, so forgive me if there are spelling mistakes. This is also my first time writing novel, so if there are mistakes, you can help me fix them:>
And lastly, I've never made a synopsis, sooo...don't make fun of me :×
--------------------------------------------------------
Kanzaki Rei, a 17 years old boy who died from being pushed by one of his classmates into an oncoming train, but not before he pulled the bastard's hand back causing them to fall together.
As a result, they both died on the spot at the same time. However, what he forgot, at that time he was still holding the hand of his childhood friend, Matsuda Ayana, who was also thrown because of her slender body.
Upon awakening, he found himself becoming a small glowing ball floating in the air.
