Only second chapter in but it's ongoing and updates seem steady. I'm going to re read it now I love it so much so far. It's basically the uke taking care of the seme though.

The nursing scene I love most in Bl is in this one..
http://www.mangago.me/read-manga/kichiku_encount/ - It's the turning point of this yaoi too.
Looking for any yaois where the uke gets sick and then the seme nurses him back to health? Or where the uke gets hurt (sprains something, breaks a bone etv.) and the seme stays with him until he's healed?
Thanks. (づ￣ ³￣)づ
