Heer=Sita(sita loves ram and lives in ram dhyan after getting kicked out of kingdom.I hope heer also remains prem's heer.I dont want her to get married to sumone else)
Preet=laxman(laxman guards sita in ram's absence so I guess the same wud be here.In ramayan ram was temporarily out.But here our prem is permanently out)
Harman=Bharath(So he takes up business responsibilities after prem)
Rishab=Ravan(ravan is back of sita ofcourse this all started as laxman kicks out ravan's sister when she tries to woo ram.There can be sum reason behind the rivalry or it can be purely business oriented.He will be back of heer may or may not be wid da same intention as ravan as frum now on heer will be taking charge of luking after junegas)
Dheer(shourya)=vibhishan(he is brother of ravan and gud guy unlike ravan.infact he helps ram in defeating ravan by letting him know how ravan will die.As I read in TB article which quotes tht dheer will turn positive as story progresses I guess he will help heer n preet in defeating rishabh)
