I wish I used Mangadex earlier just for the comments. I can't believe I had found this title very early on back then. Felt like it was just yesterday but now it has a fair amount of chapters. The characters are surprisingly likeable. Somehow refreshing. The mystery in the beginning makes us wonder, "who is the girl he is looking for?"
The title is also perfect, kinda figurative and literal, to the story.
The fact that the story is more like a dive into the past. With short breaks back to the future(present)using vague dialougue and not actually seeing who said it. I can't find myself rooting for a single girl, though slightly leaning towards the more reserved black haired girl who constantly worries about being too selfish and unfair.
With the way it's being forshadowed, I really wish this will end like Bokuben, like multiple endings.
