You need to have at least 50 KP and wait for Bree to call you around 12:00 she will invite you to go to coffee shop and she will explain to you that she doesn't have money and need a job. If you proceed this path, this will trigger Maid Bree. Otherwise if you talk to Bree at the living room around 18:00 she will invite you to an arcade tournament and this will trigger Gamer Bree.
