Do you want to read articles where authors complain about themselves? Come on then, I put all my rants here.
(The following is a formal introduction)
A man of unknown origin, a mecha with an unknown past. After meeting, sparks of love arose. He is powerful and has a home all over the world. He has no hesitation in teasing girls and fighting, and he never hesitates to give in when it is time to give in.
Maybe it's not a very cool book, but I tried to make it feel real.
