He totally heard her and then ran away from the situation rather than deal with it. The vibe that Kodaka has been putting out the last couple of eps telegraphs that he has a closeness barrier of his own that is sensitive to the direct affection of others. His scenes alone with Rika these last eps have practically screamed that he's not just dense but that he's willfully trying to deny the existence the other chars affections towards him. Rika has, in typical, infuriating, meek Japanese girl fashion, been trying to get him to recognize and acknowledge that he means a lot to her and the rest of the group, but in each case he reacted in a way more hesitant manner and tried to downplay or deny what she was getting at.
