It's only an extension of a couple living together who shouldn't be together, who do nasty things to each other as well, and blame each other for all their wrongs and ills in their life.
Hii ni endelezo tu ya wanandoa wanaoishi pamoja ambao hawafai kuwa pamoja, wanafanyiana vitu vibaya pia na wanalaumiana kwa shida zote za maisha yao.
