Ever since salary man Saki Hiroyasu passed out from fever and college student Shinomiya Jun nursed him back to health, they have only grown closer. Each time Saki frequently visits his favorite café, Jun rushes to his side to take his order, but ends up flushed in the face.

So. what exactly is Koibitogokoro? Well, it's a little complicated to explain.

If you ask me to summarize this manga in three words, they would be:

Smut, smut and smut.

The thing I sometimes, dislike in yaoi manga is the way they portray the main characters. I'm sure you may have heard many good things about this manga, like it has a nice storyline etc. but the reason I gave it an average score is because it really doesn't have much good in it. Trust me, when I say this isn't that good. The ...
