Er, what on earth makes you think that? The author's already spent 13 chapters building up the Hayato x Ryou tension. AND... Ryou is the main character.
Not yet , but there might be a high change ... I hope so ... If they're not,i might jump off a bridge (ಥ v ಥ)
There are i'm-not-gay-i'm-straight-but-i'm-in-love-with-you-anyway-characters of Yamamoto-sensei so i don't think there will be any exception for Ryou lol

Another generation http://mangapark.me/manga/honto-yajuu/s1/v7/c15.1 These two are kinda like another version of Ryou and Hayato =_=
i see there are a lot of hayato & ryou shippers here. i actually love kento & take pairing. hayato & ryou hasnt even had any romantic scenes yet so i'm wondering if hayato will be getting a new love interest
