Libertas (Koujaku x Sei) Oneshot

For those who don't know, Koujaku and Sei are from this dating sim called DRAMAtical Murder. Their pictures are on the cover of course. Also the plot is pretty simple as well: Sei is saved from the central part of Platinum Jail by Koujaku instead of Aoba. They live together and Koujaku is going to help Sei learn everything he did not during the 17 years he spent at Platinum Jail. *Libertas means Freedom in Latin
