Says he fell in love at first sight
Doesn't mention with who
Is he saying he loves Melody?

 

[Nonya22]

My good sir she is half your age.

 

[SakuraOrihime]

My good sir she is half your age.

...Ain't she like, 11 or 12, and him around 15, though...?

...Ain't she like, 11 or 12, and him around 15, though...?

I thought she was a little younger than that, and he a little older.
At 12 and 15, 3 years is still a pretty big gap in life experience though. And while the audience might know Melody has memories from her past life, it's still giving "20-y/o thinking a 16-y/o is 'very mature for her age'."
