Ruhi -the cupid of YHM preleap,the child who got swapped with the ''iron baby'' whom she also loved before she came in the world infact ruhi was the one who first wanted a child from her ishima, i agree that was a lil kid 'zid' for having a younger bro or sis But then we all know how much sensible child ruhi was, she never thought for a while about her position in her ishima life will be affected by this newborn as she was like that only full of love n care n trust for her famliy.So when she 1st came to know about the horrible truth through sarika still she had belief on her ishima even after the real deed (the exchange) she was craving for her ishima. But now after a tortures life of 7 years widout her ishima n papa she lost her faith,her physical pain must be less painful than the mental trauma as now she is not wanting to free from the clutches of that naagin and ready to forget her past her childhood her family her ishima or ishita bhalla. this addresing for her ishima shows she want to destroy herself by not revealing her truth to her ishima. her personality her pahchaan all become a delusion. she is hurt way beyond words it will take years or if cv dimag chaleyege 'bachho ki tarah' to ek din me ruhi will be normal in fututre after reunion of ishraru.
Ruhi knows both ishima n papa is alive still cant go to them, due to naaginn and in future due to her anger.
Dr ishita...bhalla/iyer?-the ishima of yhm who was a barren, a rejected girl, manhoos (a/c to society)n craving for solace through adoption but full of self confidence n was never tolerate anything wrong n a simple n sweet girl she used to be.she became ishima her first real love, her ruhi gave her the much needed solace which she was craving for and after meeting ruhi her life become full of life she got such a loveable family although it has taken time.n then raman happened he was such a bliss in her life she didn't thought she will get such a lifepartner no she didn't got a prince charming who every other girls want in der life but she got her raman who was exact opposite of her dreams but his inner self wen comes infront of her cant be more happier than this.his raman full of error but loves her most n out of the world.whether its during bhoot track or her jail trip he amazed her by his love towards her. So wen that raman accuse her of the dreadful event of der life n yelled at her by those names' from which he only saved her n directly told her to don't show her face in this lifetime, her self confidence comes down trambling without any noise n mixed wid most tragic event of her life she decided to end her existence.but fate send her to austraila n now she lives with her best friend her saviour from that suicide , she is broken from inside but gather herself for another family alia mani n nirvaan(still not shown) she pretend to be extra happy , you might think she lives happily after leaving raman but she wear a mask of pretence,shows she is extra happy, her overenthusiasm for even a dish taste make u believe she is extra happy n u might hate her (I still hate her until cv don't show her pov)but she made herself like this in these 7 yrs to cover up her pain, her agony in these loud screaming unnecessary emotions. she keeps herself well maintained to cover her mental state.
Ishita knows ruhi is no more but raman is alive still cant go to him due to guilt and his words.
Raman Kumar Bhalla-the angry young man, the puttar of YHM, who was broken due to his failed marriage and had lot of hate and anger inside, who don't want to see his own daughter due to his pain but loved her unconditionally n unnoticeable. he lost his greedy wife to a cunning boss so to show her his worth he become the business tycoon who don't need any introduction in the business world. he was not a money minded but a very sweet person who loved her wife too much but her departure bring the best in him, but only in materialistic world coz he lost his sweet nature n become a ruthless person but deep inside he was the same. The same duo (ashgun)which once destroyed his life again entered his life but this time to take his life his ruhi but then God blessed him, for his every good deed, his ishita. The women who annoyed him upto bottom of his heart from starting finally reached bottom of his heart in a such a steady manner that he didn't even realized that he is hopelessly in love with this jkr who irritates him n he, he taunts her anytime it become his favorite pass time surprisingly. The love towards her always amazed him this love is not some simple love but way beyond their mind, he knew about his weakness his big bitter mouth which caused him many problems earlier also in their married life but he thought his love is more powerful and his ishita will always understand him and forgot the harsh words which comes out of his mouth unknowingly and indeed it was this way until their lil ruhi leave dem , he couldn't control his emotions and bashed her for the misfortune, he was too broken to think wat he is yelling , he only told her to go away else he will kill her and now when she take his words seriously and leave her like ruhi he could do nothing but grieve over the loss of his life. The 7 years which passed in jiffy he only knows how he is living without any life within him, he loves pihu as she is replica of ruhi n last sign of his ishita. He consider himself a looser to lose everything due to his own mistake.
He might end up killing himself to accompany his ruhi and ishita but couldn't do it for pihu sake.
PS-I m now eagerly waiting for ishita pov. Hopt tommorow episode will reveal the true feeling of ishita n why she make mani believe that she don't think about raman as these kind of hint obviously increase mani hope to move on with her.
PPS-Raman giving importance to shagun for pihu matters only, ishita to mani due to obligation or friendship may be, ruhi to naagin due to majboori and in future may be (if cv wants) due to her revenge from her parents n self destructive mode which will very dangerous.
