This story is definitely higher than a 6.93 if the same romcom drek keeps fishing scores of 8+ on here.
The story is convoluted, yes. There certainly are plot holes and whatnot. However, some of the more egregious ones are solved. The most prominent is why Tatsumi Ratio didn't kill Tanaka. My theory at the start was that he's a descendant of Tanaka and it seems I was right given the end. Perhaps not the same way he came into being otl, but the timeline still corrected itself, thus resolving a problem with causality. To a degree, Asuka going so far back in time before all this may have caused the timeline to shift in the first place. Its evident that the leaders of the future are playing a temporal game far beyond their control as practically all the agents sent back either defected or went rogue. All their scheming and infighting only allowed Ratio, who did have the backing of people in the past, to mobilize a force string enough to change history.
There were definetly plot problems. The romance was painfully slow, even if some questions like keeping a status quo between childhood friends were good ideas. While I slowed down by reading pace midway the quick ending, perhaps from an ax, made me interested again. I also respect the childhood friend ending at all which is too rare, with other stories throwing away those female leads. I think the other female lead who fell in love handled herself well enough, but the ending with her being zombified and not appearing again did her dirty.
Sometimes a story needs to be defended for being creative. This story is certainly one of them. If I don't support stories like this then this only encourages slop to be written instead. As such, I applaud the author for their original and good, if flawed, story. An enormous shame that no english paperback exists.
8/10.
