Hazuki and the Puppy

I was just leisurely spending time in the courtyard. Then suddenly, a couple's breakup conversation happened right in front of me. Seriously, they should do this somewhere less conspicuous. Wait... both of them are men? And so began our friendship through this strange encounter. This laid-back kind of relationship isn't so bad either. A story about a plain literature university student girl and a beautiful boy, puppy-like, black-hearted gay(?). ※Homosexual characters appear in this story due to plot requirements. However, it is not the main focus. If this is not your preference, please refrain from reading.※Also, there are some crude remarks, so this is rated R-15. There are no sexual descriptions.
