No...
Even though,
I did tell about meeting Corn in Guam to. Tsuraga San.
I didn't mention about similarity of their appearance at all.
While people looking at us they see a person they have met recently or a person they mostly remember.
So in Kyoko chan's memories,
This person takes biggest part of it, that's the reason.
Because,
Most likely.
If I were to say reasons behind of Corn' appearance,
He is the one you have met recently or you are thinking about him frequently.
Needlessly at that,
Isn't it obvious, I would reveal the fact that I am thinking about Tsuraga San!!!
