Hellarie's Manga

It's so good so far but I'm so scared about the ending, the narrator (whoever it is) seems like they did such a terrible decision or went through an excruciating pain. I hope it's not as depressing as "My reason to die", I hope the ending will consist of happy moments where they are together in this specific timeline, then side stories of them with their kids. Like please give us 5 happy episodes before the epilogue. I don't think my heart will handle it if it's depressing.
