I'm not sure if it's a manga, but this is the artist: http://www.mangago.zone/r/l_search/?name=%20itsuki%20kaname
Wow. Omg, thanks! I thought I recognized the mangaka! I haven’t looked at itsuki kaname-sensei’s stuff in a long while. I’m probably going to have to reread everything because I now have a calling to make sure that I didn’t miss anything.
I know what you're talking about! Something just urges you to freakin' read everything the author has written! Glad I could help you ヾ(❀╹◡╹)ﾉ~
