Nice. Tatsu still hasn't particularly proven that he actually likes her, and instead constantly complains about her back fetish. Even though he thinks he should totally be free to indulge his hair fetish at any time.
Oh, also she can't want sex because she's a woman and that's just weird.
Tatsu demands a lot out of Kotoka without really offering much.
Think back to the date chapters, he managed to have a totally normal and romantic date with Mash but his date with Kotoka was just UHHHHHHH HAIR
