Typical story line , uke that doesn't want to be in seme's way so leave him ..

I agree. I was hoping that Kashii would have handled the issue in a different way but then I wasn't surprised when he chose to leave Yoshika because I knew down the road they will be facing it in a mature manner that perhaps will be cliché like any other but still has that punch because this is a Tenzen Momoko's work where there's a lot of substance in every panel. It's just how I feel about it and that's why I am still reading this and will see this until the end.
