Well, to be honest with you, I don't know what to say...
I have close girlfriend who is 30 years old now, but very short & small (145cm, not dwarfism), face & body looks like 12-14 years old.
Her husband is 180cm, body build slightly bigger than average asian guy, he is 32 years old.
They got 2 children now.
They start dating during High School, she get married to him at 20.
.......
Like, if I can turn her into anime image, she looks exactly like Rurin, just not act childish.
Same height, same weight, same body type, same black hair, same hair lenght, same straight hair, and similar face shape.
Wow such a letdown. No matter how good the story is, if the romance dynamic is like this then it's time for me to drop it. Why are the authors so obssess with these kind of pedo type of troupe. Imagine, being an adult and blushing for someone who looks like half of your age
