Sabita Yoru Demo Koi Wa Sasayaku
Azami (Prequel/Sequel) Renai Rubi no Tadashii Furikata (Spin-Off) Hadakeru Kaibutsu (Spin off) Azami is doujinshi written after it's sequel (this story) so my recommendation is to read this one first, Azami is there to help you understand their relationships better.
