In the first part of 'Beloved' by Toni Morrison, Sethe lives in 124 with her daughter Denver and her lover Paul D after the departure of her two sons. The arrival of Beloved, who resembles Sethe's deceased daughter, creates tension as Paul D becomes increasingly uneasy and ultimately leaves Sethe after confronting her past. In the subsequent sections, Sethe's relationship with Beloved intensifies, leading to financial ruin and dependence, but Denver eventually seeks help and becomes independent after Beloved mysteriously disappears.
