This manga will overturn all of your prejudice towards Age gap couple, especially those with the Older Woman. Most people directly judge that when a man marry a woman much older than him, then the man was a scum, gold digger, a gigolo, whereas the woman must be rich, stupid, and just want young blood.
And yet, this manga will slap your prejudice that, NOPE! Love can be born even within the ridiculous age gap of 18 years! And will also tell you the story that even such a couple could be born with acceptable romance story...
