I suspect he's left a string of broken-hearted girls behind. When he was younger, he probably complained occasionally about not being able get a date and his friends all went
. He seems really dense, ya know? And he's really focused on cooking. I remember how he looked/sound in episode 4 when Ren called Tooru in to show his new dish. His face brightened and he practically bounced inside. I thought it was adorable.
They have to give us a Tooru ep sometime. I'll even settle for a general kitchen ep at this point. Maybe as Tooru and Ohana get to know each other better, PA will sneak in some Tooru tidbits?
(And now, off to bed with me!)
