if you like seinen and yaoi, this manga is for you.
The story is not focus on the relationship between two main characters which fall in love but contains a very interesting plot about Yakuzas and gang war.
All the characters in this manga are in deep pain and you will be too by knowing their stories. I think that Kyugo has really managed to make them all very humans and even though you haven't experienced the same things they have, you can trully identify yourself and understand their feelings.
It's a hard story but i can't wait for next chapter!
I recommand it at 100%.
