**Saira** ek joint family mein Mumbai mein rehti hai, jahan uska jeevan apne pyaare parivar ke saath bit raha hai. Uske padosi, **Arjun**, ek ambitious aur intelligent insaan hai, jo apne sapno ko paane ke liye hard work kar raha hai. Jab Saira ke father **Mr. Sharma** ko Saira ke college ki grades ke baare mein tension hoti hai, toh woh Arjun se request karte hain ki woh Saira ko padhai mein help kare.
Arjun aur Saira ke beech dosti badh kar pyaar mein badal jati hai. Lekin Arjun apne dil mein ek darr rakhta hai. Woh apne aur Saira ke social-class difference ke kaaran uske parivaar ke rejection se ghabrata hai, aur isliye woh apni feelings ko express nahi kar paata. Saira ke parents ek aur ladke, **Vikram**, ka proposal accept kar lete hain, bina jaane ki woh ek spoiled, alcoholic, aur gambler hai.
Vikram ke saath shadi ke pehle, Arjun Saira ko alvida kehne jata hai. Lekin is beech, Arjun par ilzaam lagta hai ki usne Saira ko bhagane ki koshish ki hai. Jab yeh misunderstanding clear hoti hai, Arjun Mumbai chhod kar Karachi chale jata hai apne dost **Rafi** ke firm mein kaam karne ke liye. Karachi mein, Arjun Rafi ke beemar father **Rehman** se milta hai, jo apni condition ke bawajood ghar mein accha treatment nahi paate.
Arjun aur Rehman ke beech ek gehra rishta ban jata hai. Rehman ki health deteriorate hoti rehti hai, aur Arjun uska khayal rakhta hai. Is beech, Saira ki shadi Vikram ke saath ho jati hai, jo uske liye ek nightmare ban jata hai. Vikram ek abusive husband aur gambling addict niklta hai. Arjun, Karachi mein, Nisha ke ilzaamon aur ghar ke problems ke beech ghira hota hai, lekin woh apne principles par bana rehta hai aur Rehman ke saath apna bond banaye rakhta hai.
Rehman ke death ke baad, Arjun apne aapko broken aur alone mehsoos karta hai. Lekin Rehman ne uske liye ek gift chhoda hota hai — ek high-value plot of land ke papers, jisse Arjun apna naya business shuru karta hai. Ek saal baad, Arjun ek successful aur wealthy businessman ban jata hai, jabki Saira apni zindagi Vikram ke abusive nature aur do bacchon ke saath bita rahi hoti hai.
Teen saal baad, Arjun apne naye employee **Naina** ko hire karta hai, jo usse chupke se pyaar kar baithti hai. Naina apni zindagi ko Arjun ke saath jodne lagti hai, lekin Arjun apni purani galtiyon aur Saira ki yaadon se ghira rehta hai.
Vikram ki gambling addiction uski zindagi aur bhi bigaad deti hai, aur finally, woh Saira aur unke bachon ko chhod kar chale jata hai. Jab Saira aur Arjun phir se milte hain, toh Arjun Saira ke broken aur ruined state ko dekh kar devastated hota hai. Uska care Saira ke liye Naina ki jealousy aur insecurities ko aur bhi badha deta hai. Arjun apne past ke galtiyon ko sudharne ki koshish karta hai, lekin waqt ne Saira ke dil par jo zakham diye hain, woh ab bhi hara hain.
Arjun aur Saira ki zindagi ke mod unhe ek doosre ke kareeb le aate hain, lekin unke beech ke dard aur gile ab unke raaste mein rukawat ban jate hain. Kya woh apni purani galtiyon se seekh kar apni zindagi mein khushi dhoondh paayenge, ya phir waqt ne unke liye sirf dard hi likha hai?
