Interesting way to end the series, with an implied off screen death of the title character. I do like how this ends though, with Gilbert basically saying that this time magic isn't needed; that he lived a happy enough life that he doesn't feel the need to redo anything. Basically, Aster's gambit worked well enough in the end, that the cycle of time loops are broken.
You all know this, but I utterly love this story. I wish there were more of it, but I am glad it came and went the way it is. The art style is very simplified compared to other manwha, but I still enjoyed it.
Wish I could give it a 12 out of 10 in my trackers.
