Viren, Naina and Raina share a moment. Viren has to leave for Bangalore and therefore, he asks Vineet to stay with Naina and Raina. Vineet who has already taken the family to their old house, which happens to be the sisters' home, they're happy. Viren is happy until Naina is happy. And the house they are in is a house of memories of Naina's elder sister, who stood by their side when his own parents turned away from him. Viren feels a little relieved to have Vineet around them. The guy has promised him to stay with Naina and Raina until Viren comes back home.

Little Raina is disappointed to find her parents and bade papa busy on the phone. She makes a sour face at which Vineet scoops her in his arms. He kisses her cheek.

"Kya hua Raina ko?" He asks softly.

"Raina gussa hain!" The little girl says grumpily.

"Arey kyun? Maine kya kiya?" Vineet asks innocently, though he knows that he has been talking on phone.

Little Raina gets cranky if her parents talk on the phone when they are with her. She needs all the attention on herself, be it she is with her father, mother or bade papa. She reminds Vineet of her aunt Raina. Little Raina is surely the replica of the love of his life. Vineet smiles and tells Raina that he will take her to the beach and also buy her a balloon, in the same way, he used to do for his Raina.

Meanwhile, Naina comes out of her room and glances at her daughter. The little girl turns her face away. Naina is astonished.

"Arey! Maine kya kiya?" Naina asks.

"Aapne Raina ko akele chod diya!" The girl replies making a sad face.

"Par important call tha na, baby! Aur waise bhi aaj se mumma aur Raina bahut maze karenge na!" Naina pats her cheeks.

"No no! Raina aapse gusha hain. Bade papa, chalo! Hum beach pe jayenge." Raina looks at Vineet, still cradled in his arms.

Vineet smiles while Naina looks at them. He frees Raina on the floor and asks her to wait in the living room. The little girl runs into the living room and sits beside her dad, who's still on call. Vineet glances at her and whispers in her ears.

"She's still the same, Naina! Main isme tumhari behen ka aks dekh sakta hoon. Isey apne itne kareeb rakhna ki ye kabhi tumse door na ho! Raina thik hi kehti thi, wo hamare beech na hokar bhi yahin rahegi! Vaada nibha diya usne!" Vineet says softly and his words leave her astonished and he leaves taking Raina with him.

"You're right, jeeju! She promised me that she will be by my side, forever." Naina whispers to herself and trails back into the past.

*Flashback Begins*

It's the time when Raina has been quite busy in her office. She's working with Vineet in his office and there's a deal on which Raina is asked to work. Actually, it's a certain someone, whom Raina didn't like at the first meeting. It's evening and Raina is sitting on the couch, lost in some thoughts. Her trance is broken when Naina sits by her side. She has been noticing that something is bothering her sister, but she doesn't know what it is.

"Di, are you okay?" Naina asks her sister.

"Yes!" Raina replies instantly as she takes the coffee cup from her sister's hand.

"Lagte toh nahi, Kuch hua office mein? Ya jiju se ladai?" Naina asks, reading her sisters' expressions.

"Kuch nahi Nain! Bas ek project ke baare mein soch rahi thi." Raina says, sighing deeply.

"Arey! Kaam ke baare mein aap itne tensed kyun ho? Maine aapko kabhi aise nahi dekha. Batao na, kya hua?" Naina asks again.

"Kabhi kabhi tension ho jata hain, Naina! Jab kaam aapki pasand ka na ho ya jab kaam karne walon se dikkat ho! Lekin tu tension mat le! Tu bata, tera college kaisa ja raha hain? All good?" Raina asks, fixing her gaze on Naina.

"Mast! Riya is a good friend, aur wo bandar! Wo Viren! Roz pange leta hain mujhse!" Bulbul makes a face.

"Tu college padhne jaati hain ya usse pange lene?" Raina rolls her eyes at Naina.

"Arey! Wo pange leta hain! Kitni baar bola hai usko, mere aaspas bhi na dikhe! Fir bhi aata hain! Annoying creature!" Naina makes a face.

"Kahin usey meri behna pasand toh nahi aa gayi?" Raina winks at her sister.

"Pasand! Eh! Wo mujhe thik se jaanta bhi nahi! Aur mujhe toh wo katai pasand nahi hain! Toh aap uske baare mein baat nahi karo, samjhi!" Naina says causing Raina to laugh.

"Acha relax! Tu fresh ho ja! Main khana banati hoon." Raina says and turns to leave.

Naina holds her hand. Raina looks at her and Naina makes her sit again and hugs her, keeping her head on her chest.

Raina is astonished but she hugs her back and kisses her head. She continues smearing her head and asks her.

"Kya hua tujhe? Sab thik hai na?" Raina asks, her chin still placed on her head.

"Bas aise hi aapko hug karne ka mann kiya!" Naina says, parting the hug.

"Tu sach keh rahi hain na?" Raina rolls her eyes at her baby sister.

"Yass Di! Bas aise hi mann kiya! After all aapne mujhse promise kiya hain na ki hum hamesha sath rahenge!" Naina looks at Raina hopefully.

"Han Naina! Tujhe toh pata hi hain main apne vaade kabhi nahi todti. Tujhe kya lagta hain main tere bina reh paungi?" Raina asks, boring her eyes into Naina's.

" Pata nai di, lekin itna tay hain ki main aapke bina nahi reh paungi. Kabhi kabhi mujhe lagta hai ki aap kahin chali jaogi!" Naina says, confessing her true feelings.

Maybe, that is because of Vineet and Raina's relationship. For Naina, Raina has been her mom and sister both. She doesn't want to lose her and upon seeing the closeness between her sister and Vineet, she is fearful. Today, she said it all. Raina cups Naina's face.

"Tujhe ye lagta hain ki main kisi aur ke liye tujhe chod dungi?" Raina asks, but Naina doesn't respond. Though, in her heart, she feels that her sister might leave her for her love.

"Tujhe pata hain mere liye tu wo tohfa hain jisey bhagwan ne bheja hain. Mumma ne mujhse kaha tha ki bhagwan sabki wish puri karte hain aur pata hain maine unse wish maangi ki mujhe chota bhai ya behen chahiye, aur uske baad tu mili mujhe. Tera janam hi mera tohfa hai. God granted my wish and sent you. Isliye tu mere liye precious hain. Tu aisa soch bhi kaise sakti hain ki main tujhe chod ke kahin chali jaungi." Raina says.

"Mere liye tu sabse pehle hain, Naina! Baaki sab baad mein! Vineet bhi! Han shayad dosti se kuch zyada hain lekin tujhse zaroori ya tujhse keemti nahi hain wo, Naina! Ye baat Vineet ache se jaanta hain. Isliye tu chinta mat kar, teri Di tujhe chod ke kahin nahi jayegi." Raina says, her eyes are teary.

Naina hugs her sister again. Yes! She thought that Vineet may ask for Raina's hand in marriage and her sister will leave her alone. But, it's not the case, it seems. Raina and Vineet share a unique bond of love, where they are connected by soul. They don't need to give tests to prove their love. Raina hugs Naina and smiles.

"Tu chinta mat kar! Main hamesha tere sath hoon. Aur agar kuch hota bhi hain, kuch aisa ho jaye jispe mera bhi control na raha, toh bhi main tere pas rahungi. Ye mera vaada hain tujhse!" Raina says and she kisses Naina's head.

"Sach mein na! " Naina confirms.

"Han! Tu chahe toh main aatma ban ke tujhe sata dungi!" Raina finishes her statement playfully at which Naina slaps her arm.

"Shut up , Di! Kuch bhi kehte ho! Aisi baatein na kia karo aap! Aap bas hamesha mere sath rehna!" Naina says holding her hands.

"Main na sahi! Koi toh zaroor rahega tere pas, mera aks ban kar." Raina says softly and the sisters share some moments together.

*Flashback Ends*

Naina comes out of her trance and her eyes are teary. She finds Viren standing beside her. His gaze is fixed on her and he asks the matter.

"Viren! Di ne kaha tha ki unka aks hamesha mere sath rahega! See, she kept her promise. Jiju ne bhi yahi kaha! Is baar kuch nahi hoga na, Viren? Kuch galat nahi hoga na?" Naina looks at her husband.

"Nahi Naina! Jo hua wo ab nahi hoga! Hamari Raina ko kuch nahi hoga. I know, meri wajah se Di...." Viren says but Naina keeps her finger on his lips.

"Shh! Tumhari wajah se kuch nahi hua, Viren. Sab kismat ka khel hain! Lekin jo galat hua hain usey hum sahi karenge! Tum mera sath doge na?" Naina asks, holding his hand in hers.

"Of course Naina! Main hamesha tumhare sath hoon." Viren says and embraces Naina in his arms.

Naina sighs deeply and relaxes in his embrace. After a while, he leaves for the airport and asks Naina to take care. Vineet has taken Raina to the beach. Naina instructs the maid to prepare raw materials for making noodles, as her little one loves noodles. The maid nods and Naina moves to her room.

She sits on the bed and her eyes fall on the diary which Vineet has given her, her sister's diary. She opens it and turns a few pages, where something is written in red ink. Naina is astonished to read the words and is lost in the moment.

To Be Continued.

What's the secret that Viren and Naina hold?
