Even though the story didn't end the way I wanted or hoped to end, it deserves 10/10. The art is beautiful and the story is well written, you can feel, that the author really thought it through.
SPOILER:
Regarding the ending. I understand that this was the author's decision, to make the ending like that, but I just can't understand the characters. I mean if they really loved each other that much as they claimed it, how could they be apart for so long or even be fine with never meeting again... Maybe that's the only thing I'm missing from the story. The thoughts and feelings of Gene, while he was apart. Did he really never plan to go back to Trevor? Okay, he wanted to study, explore, find himself, etc. but was he really okay with never seeing someone he loved so much? Trevor's side I can understand it a little bit better because of the journal.
Then they meet again by luck (so to say). And yeah, after so many years, feelings can change, so it could be they don't love each other anymore, it is just friendship. But I think you should be able to decide, which one. If it's still love, maybe you need some time to catch up on with each other because of being apart for so long, but then get back together. However, if it's not LOVE, just LIKE, why moving together..? Hmmm..
I just feel sorry, because it feels like they still love each other, and loved each other all along, but they wasted sooo many years for being apart.
But that's just my POV.
Still loved the manga
