Ereba

Ereba is an asari merchant on Illium. She runs the store, Memories of Illium, that sells model starships and fish. She is currently the target of the love-struck krogan Charr who stands nearby reciting poetry.

Mass Effect 2
Ereba was in a relationship with Charr but broke it off with him because she was not sure of what he wanted. She thinks that Charr may only be interested in her so that he can have children (Ereba notes that krogan whose reproduction has been adversely affected by the genophage may only procreate with asari). Commander Shepard can either persuade her to take back Charr or to forget about him. Regardless of the outcome, Ereba will give Shepard a discount at her store. If Shepard helps get the couple back together, they travel to Tuchanka together to start a new life. As a result, the two can be seen again on Tuchanka if Shepard convinces Ereba to settle down with the krogan, but no further interaction can be made with them.

Mass Effect 3
If Shepard persuades Ereba to continue her relationship with Charr, she can be found on the Citadel in the Presidium Commons. She mentions that Charr, now her husband, is off fighting in the war against the Reapers.
