A father (Kazui) and son (Kei) love each other dearly. But when Emily, a girl from Kazui’s past, visits them in Japan, their relationship starts to crumble under the threat of their own thoughts. . .
there is also another one by the same name scanlated by nodeadline by the same author but a whole different story.
Basically one doctor is in love with kazui (not sure if it’s the same one from nakama version,) and another dr is in love with him, it’s quite a sad and tragic story, but its a good one.
