No wonder it got axed after 18 chapters. Male lead is around 15-16 acts like a 12y old. Fiancée is an elf who is over 500y acts mostly as a weird older woman with occasional hard turns towards infant like behaviour.
I'm not even talking about plot....there isn't one just a pure reactive and dumb comedy about people who act lower than their age.
obviously they're going for a more wholesome romance but i can't shake off the idea that this is grooming, she's instilled this dating idea since he was a child (and just because she's attractive doesn't mean it's justified, japanese authors.)
