How to unlock the Paramour achievement in Mass Effect - Definitive Guide
If you are female this will include Kaiden or Liara.
After each main planet mission (Feros, Noveria, and Virmire) when you find yourself back on the Normandy find which character you want to get with and have a conversation with them.
Then on your way to Ilos the event will take place and the achievement will unlock.
Possible love interests:
===================
Male Shepard: Ashley, Liara
Female Shepard: Kaidan, Liara
In order to progress the romance you will have to pay your chosen one a visit after each main mission. So as soon as you're back on the Normandy...the two of you will have to talk.
Throughout the game, you can talk to all of your squad members and learn about them. Certain squad members, if you talk with them enough, you can eventually romance. Who you can romance depends on the gender you choose to be, but the romance options are as follows.
Male Shepard: Ashley Williams, Liara T'Soni
Female Shepard: Kaidan Alenko, Liara T'Soni
Whoever you decide to romance, make sure you talk with them after every story mission, and always choose paragon or neutral choices so as to keep the romance going. Even after they express interest, nothing will happen until the end of the game. Once you finally are able to go to Illos, your romantic interest will approach you. Continue to be supportive and eventually you will be given the option to invite them in for the night. Once the scene plays out, you will unlock the achievement.
