the older you get the less you worry about age. I'm 33, 34 on the 9th May. My boyfriend is 42. My parents had an age gap of 11 years. A friend of my landlandy and is in her 30s and married someone in their 50s. It gets to the point wherein age stops mattering.

There are reasons that an adult (Kaito) and Miku (a teenager) may seem creepy, because Miku is still "an innocent" and at 16 doesn't know much about the world.

I will note that Kaito has no official age so "20" is just as nonsense as "40".
