To the people complaining about how rape was treated. To me it seems like a parody of the "I love you so I will rape you" trope. Reo obviously loves him, so he rapes him (something often happening in older yaoi) without considering his feelings and then assumes they are dating because the uke is too scared to go against him (which he is completely oblivious of and probably thinks it was consensual too).
