Do you think Kyoko will be happy when she finds out who ren is or not? Just curious as to ...

i kind of feel like she would be happy. I feel like she would understand his reasoning if he explains it to her but if he don't she might feel betrayed

I don't think she'll feel betrayed. I think she'll be like "YES! SEMPAI IS MY FAIRY!!!

LOL

If it were me, my mind would be like:
REN -> CORN
CORN -> KUON
KUON'S DAD -> MY DAD
LETS GET MARRIED!

LOL, but that's just me.
