>>3093330He doesn't see Ichigo in a sexual manner and she sisterzoned herself. Just further how dead in the water a Ichigo romance would be.
He saw 02's everything in episode 1 but he didn't know her then, now that they know are doing things together he is more nervous.
That said, he better initiate something soon like kiss her because it's going to get annoying if we are waiting 5 episodes for a proper post confession kiss.
>>3093342He probably didn't want be rude, just thought he was talking to a friend instead of dealing with the clingy girl that can't accept she lost.
