Takumi Saito's NOT gay.his exgirlfriend was megumi okina in 2006/2007
but they broke up later according to some rumors He dated with Aya Kiguchi
and Now , I read that He have a model girlfriend (maybe from his ageny) , they say she hot!
Takumi Saito acted in many other movies& tv shows they're way different with heterosexual themes, he doesn't always act this kind of movies,he's a verstile actor,it's acting! why some ppl always susbect a guy or girl if they act this role?
*a spoiler* to those who asked about the end, i think it's that Ryu won't appear again in Noboru's mind since he said 2 Hayase"i'm glad he found someone 2 take care of him finally", and Noboru&Hayase's relation is becoming like N&Ry's was.
