This is an age-gap adult one-shot, "simple and obvious but not the worst" plot with a happy ending and nice art. If those are things you like you'll like this 10 min read.
I usually make short reviews on manga and anime answering Yes or NO to the questions:
Is the ending good? YES
Does the main couple end together? YES
Is it worth my time? YES, only because it's a one-shot
If you like this kind of review I try my best to write in all animes and mangas I've experienced, so you can see a complete list of reviews next to my name just above.
Thank you, you're welcome and peace out. ^^
