User blog comment:Tounami/Who do you think Endou's going to be married to?/@comment-2108497-20110627080239

The official options were Aki, Natsumi and Fuyuka (it was revealed by Hino after the third game came out). Aki can't be, since we've seen her already, and that leaves us with Natsumi and Fuyuka. My bet goes to Fuyuka because there's one official image for Ogre with Endou, Fuyuka, Kanon and Kanon's coach (IIRC). I guess that was a hint to show us who Endou got married to.
