Sora better not have a crush on Ryouta. If he does the poor child will be heartbrokened when he realizes that he can't have Ryouta.
Ryouta belongs to Acchan.
Acchan belongs to Ryouta.
And it has to stay like that.
Hopefully he'll find someone BETTER at least so he'll keep his mind off of Ryouta.
And so Sora will be happy and live the life with the person he loves that isn't Ryouta.
