In short, It is wholesome.
When you hear about reincarnation as a premise, you start thinking about the legions of poorly written modern isekai mangas that became common in the recent years. This one is different.
Here, we have realistic characters, and the manga touches many adult topics, aging, loss, dreams and so on. A kid or a teen probbaly won't appreciate it much, but a grown up adult is much more likely to enjoy it. Honestly, If you think about it, it reminded me of Pixar's "UP" somewhat. Although the premise wasn't as tragic.
7/10 Story, 6/10 Art, 7/10 character, 7/10 enjoyment, 7/10 overall.
Story - the work takes itself seriously, and despite characters occasionally being somewhat stereotypical on occasion, manages to touch many topics suitable for adult people. It is heartwarming at times, sad at times, and basically it can touch heart strings of a grown up, which means it is quite good.
Art is okay. It is good, the amount of detail is decent, but it doesn't exactly standout otherwise, it just does its job.
Characters are portrayed more or less realistically, with focus on the main character. Can't say they're completely lifelike but they're believable, likable, and the manga does a good job portraying age differences well.
I enjoyed it.
Overall, it was a hidden gem I accidentally found whille looking through the piles of trash mangas, manhwas, and manhuas where every single one of them was about some sort of harem, overpowered protagonist, cheat powers and whatever else. Instead I found this by accident, and enjoyed it very much.
I highly recommend this title.
