I really don't remember...

I have bad memory, sometimes it scares me. The manga I remember to really like when I first enter in this amazing world which is Yaoi is Kizuna by Kodaka Kazuma, one of my favorite mangakas. I really like the plot and characters in the story Kei and Ranmaru are so cute together. Kizuna holds a special place in my heart. I'm not really sure if it was my first yaoi manga but whatever.
With this manga my Yakuza fetish started in yaoi mangas (▰˘◡˘▰)
I totally recommend this manga and the OVA.
