Originally I had no issues with this story, but after recently looking through the mangaka's other works, I'm boycotting anything they've written. They normalize adults with minors and I cannot support anything they write.
read one chapter when mc's friend told her that she and her husband should be doing more than holding hands and the mc said her husband wasn't "crude like that", I just... couldn't keep reading... how is it crude to kiss and have sex with your wife... to whom you're MARRIED...? jfc. that's so fucking dumb. no wonder Japan's birth rate is declining
There is actually a chapter 5, which is the end of this manga, unfortunately there seems to be no English version of this last chapter so far. If you can read in Mandarin then you can go check Chinese manga websites, chapter 5 is there.
