I forgot about this it's been so long since the first chapter was translated. I assumed this was something new. It's not and unless a new group picks it up don't get your hopes up.
@Kronix I could spoil you as I just finished reading this one, it's not a "bad" ending but a really bitter one. (and I was not really satisfied with it but at least it makes sense)
Too bad this manga isn't translated in English, it's a good one. Was worth reading.
@mitch6ll I'll have to read it again to remember it clearly but (MAJOR SPOILER)
as far as I can remember (maybe I am thinking of some other manga which have a similar story), the main guy go back and forth in time because of some power, making him go to one random day of the month each time. This power is given to children born on his birthday day. The main girl also have this power. She dies in one of the first chapters. They try to save her from dying. In the end, to save her, they need to make it as if they never met in the beginning, so the protagonist chose to save her while he loved her.
And what I don't like is the fact that
the culprit is actually their friend that have some understanding of their power (or have the same power, can't remember), and in the end no one knows it was him so he's just free.
