Yeah I know what you mean. At first I just thought that Kenji is only a huge Tsundere but his behaivor really starts to anoy me. I feel bad for Yocchan who just wants him to be a little nice to him or Kenji to say that he actually likes him and that he's not just his plaything.
Kenjis attitude is horrible im honestly starting to want Yocchan with some else because its just sad watching him get rejected all the time v.v
