Aida Saki manga
Kurata Izumi's memories of Takatsudo Shin end at middle school graduation when Shin told Izumi he never wants to see him again. Now Izumi is a single father whose son is in love with Shin's nephew. They're forced to interact, but Shin doesn't seem to remember what he said to Izumi. Add Izumi's yakuza brother-in-law Sawaragi into the mix...
Yuuto Lenix, a former DEA investigator was arrested by a false accusation of killing his own partner. The FBI agents gave him a special deal, to look for a particular criminal hiding in the same prison. By the time he was detained in the Schelger Prison, he got to meet his cellmate, Dick Burnford, who didn't show signs of being kind and welcoming upon his arrival. Will he ever be in good terms with his inmates, especially to Dick?
Here we get to follow a story about Sawaragi from Takaga Koi daro. Continues the story of Sawaragi-san after his jail time. Having been sentenced to 5 years in prison for dealing drugs, yakuza Kyousuke Sawaragi just wants to finish his sentence and start a nice normal life far away from his past. So after parole, when he literally runs into former cellmate Shuuya, he's in no hurry to renew their acquaintance. Fate seems to have other ideas though, having the yakuza and Shuuya repeatedly cross paths with him. Can he really turn his back on all of it, especially if it holds out his one chance at finding true love? It's exciting romance as only the famed Saki Aida (S) can write it and Yugi Yamada (Close the Last Door) can draw it!
