''[[Cohabitation]]''}} is a Japanese [[Eroge|adult]] [[social simulation game]] developed by [[Tactics (company)|Tactics]], a brand of [[Nexton]]. It was released on May 23, 1997 for [[Microsoft Windows|Windows]] [[Personal computer|PCs]], the same day as ''[[To Heart]]'' by [[Leaf (company)|Leaf]]. The [[gameplay]] in ''Dōsei'' follows a [[Nonlinear gameplay#Branching storylines|branching plot line]] which offers pre-determined scenarios with courses of interaction, and focuses on the appeal of the sole female main character Manami Minase. The player assumes the role of protagonist Masaki Yamada who is living with Manami shortly after they have graduated from high school. Masaki earns money at a job, and when he returns home will have sex with Manami often; this process of work in the day, and sex at night repeats many times throughout gameplay.
''Dōsei'' was re-released on September 14, 2000, with the title ''Dōsei Memorial Selection''. The game's original soundtrack was released bundled with ''[[Moon (visual novel)|Moon]]''{{'s}} soundtrack in August 2000 at [[Comiket|Comiket 58]]. Four of the staff that created the game—[[Itaru Hinoue]], [[Shinji Orito]], Miracle Mikipon, and Shinory—later became four of the founding members of the [[visual novel]] brand [[Key (company)|Key]].
==Gameplay and plot== [[File:Dōsei screenshot.jpg|thumb|200px|left|Text in ''Dōsei'' is displayed in a dialog box, here depicting the player character talking with Manami.]] ''Dōsei'' is a [[Romance (love)|romance]] [[social simulation game]] in which the player assumes the role of Masaki Yamada. Much of its [[gameplay]] is spent on reading the story's [[narrative]] and [[dialogue]]. ''Dōsei'' follows a [[Nonlinear gameplay#Branching storylines|branching plot line]] with multiple endings, and depending on the decisions that the player makes during the game, the plot will progress in a specific direction. Throughout gameplay, the player is given multiple options to choose from, and text progression pauses at these points until a choice is made. To view all plot lines in their entirety, the player will have to replay the game multiple times and choose different choices to further the plot to an alternate direction.
The story begins on Sunday September 14, 1997 with two main characters shortly after graduating high school who are living together.<ref name="review">{{cite web|url=http://homepage2.nifty.com/xgamestation/review/1997/dosei.htm|title=''Dōsei'' review|access-date=April 6, 2008|language=Japanese|url-status=dead|archive-url=https://archive.today/20130104040924/http://homepage2.nifty.com/xgamestation/review/1997/dosei.htm|archive-date=January 4, 2013}}</ref> They are, the protagonist {{Nihongo|Masaki Yamada|山田 まさき|Yamada Masaki}} and the heroine {{Nihongo|Manami Minase|皆瀬 まなみ|Minase Manami}} who he is living with; both characters' names can be altered to anything the player chooses. There are two parameters related to Masaki and Manami which change depending on decisions the player makes during gameplay. Masaki's parameters are physical and emotional strength, and Manami's parameters are degrees of affection and lewdness. How much money the protagonist has from his job is also a factor in the game;<ref name="review" /> the player starts out with 100,000 [[Japanese yen|yen]].
There are numerous scenes with sexual [[Computer graphics|CGs]] depicting Masaki and Manami having sex. Typically, Masaki will come home from work and will have sex with Manami after a short conversation with her. This continuously repeats many times, causing much of the gameplay to occur during sex scenes. Depending on the choices, the protagonist may even become unfaithful to Manami which is when more sex scenes with five different women can be viewed. The player is occasionally given the opportunity to rest, but if Masaki rests too much then he will soon go bankrupt and the game will end.<ref name="review" />
