They started with Hareb and Ayla's shadi. They were colleagues and I think they through conversations tells us Ayla fell in love with Hateb and convinced him of marriage (something like that). After marriage Aila's mental instability starts coming out. She is terriblry possessive of Hareb,can't even stand him talking to another girl. He realizes she has mental issues, they drift apart and get separated. Hareb comes close to his neighbor Aahn. Aahn is the goody goody type person. Ayla find out about their closeness and targets them and try to destroy them. Aahn gets engaged to a guy etc etc. Hareb falls for Aahn and finally they show Hareb realizing how he was not a good husband in supporting Ayla and helping her through her sickness. They show Ayla getting cured of her mental condition with Hareb's support as well as Aahn's and accepting Hateb and Ann as a couple.
It is very much possible we will see something like this with Beyhadh. By the way Maya is so much better than Ayla. Could be because of the depth beyhadh is taking us through with the characters.
