Flashback:

In Mumbai college. When Abhinavi and Kaira were in final year. After attending lectures. They all went to canteen. While having lunch they were teasing each other, pulling each other's leg. One of Abhi's classmate came there.

Person: Abhishek tumhe Rahul Sir bhula rahe hain abhi chemistry lab me.
Abhi: Okay dude thanks.

Person left. Abhishek went in chemistry lab to find no one. He called sir's name a few times but no response.

Out of nowhere, A chemical explosion took place in chemistry lab. In no time, fire spreads there in lab. Abhi got stuck in it. He was trying to come out of lab. Many studies who were nearby, gathered around.

Meanwhile in canteen. After Abhi left.

Naira (confuse): Arey! Rahul sir is on leave today.
Kartik: Oh! But tumhe kaise pata? You are his assistant? Or wait you are spying on him?

He asked to tease her.

Vaish: Kisi ne prank kiya hain Abhi par phir.
Naira (massaging her wrist): Main tumhare sare daant tod dugi kartik. Aese faltu me irritate kiya to.
Vaish (laughing): Arey re!! Kartik to Jawani me hi old age ke maze lena chahte hain.
Kartik (roll his eyes): Maine sirf pucha tumhe kaise pata?
Naira (raising her eyebrow): Sirf pucha?
Kartik (surrending himself): Acha baba tumhe thora irritate kar raha tha. I am sorry.
Naira: Haan to main-

Naira got quiet as they heard student shouting.

Student (shouting): Chemistry lab me aag lag gayi.

Listening this, everyone got shock. Kartik, Naira and Vaish quickly ran towards chemistry lab. After looking at chemistry lab. Floor slipped under their feet. Whole chemistry lab was burnt. Only fire lashes were left. Though college facilities already used fire extinguishers but chemical explosion took hardly few seconds to destroy everything.

Principal (took deep breath of relief): Students everything is under control. Get back to your studies. Chemistry lab will be close for sometime as we need some days to settle it.
Kartik (shout in anger): Sir my friend Abhishek was inside how can you say everything is under control.

Listening this principal got shock. Pushing principal side. Kartik, Naira and Vaish ran inside. Principal and teachers to came inside. Some teachers controlling other students outside.

They found a burnt body inside. Kartik, Naira and Vaish went numb. Not able to accept it. Vaish fell down on her knees. Being orphan. She never got love of family. Finally after many years she got Abhishek. As hope of her new and happy life. A person who can give her family and family's love. He died.

Just then Kartik's phone rang. He somehow took out his phone from pocket but looking at caller I'd phone fell down from his hand. It was Ram uncle.

After a minute. Naira's phone rang. She saw caller I'd Abhi's mom. She was shocked. She went out of chemistry lab and received the call.

Vibha (sobbing): Abhi... Naira mera abhi theek hain na? Hume pata chala chemistry lab me attack hua jab vo chemistry lab me tha. How he is? Uska phone band aa raha hain. Tum do usko phone.

Naira was numb. She was registering who situation in her brain.

Shila took phone from Vibha's hand.

Shila (angrily): Vibha tu chup kar. Mujhe pata hain mera Veer bilkul theek hain. Naira bacha tu usko phone de. Or haan pehle mere taraf se ek zor se thapar lagana. Aese kaise phone band karke baitha hain. Tu phone de usko.

Not knowing what to do Naira decline the call. They three were not in senses to do anything.

From Kingdom. Prime minister arranged and bring that dead body in kingdom. Though no one was ready for it but have to do death rituals. Everyone's heart broke into pieces listening their Yuvraj Abhishek died. Nigam family was in trauma. Kartik came in Jaipur for death rituals of his best friend.

Naira stayed in Mumbai with Vaish as Vaish was not in condition to go for Abhi's death rituals.

After two days. Kartik came back in Mumbai because his mind has questions for which he want answers first.

Questions like: 1. If Rahul sir was on leave then who called abhi in chemistry lab?
2. If it's prank then how this chemical explosion took place?
3. It's been more than 20mins for break then how this explosion took place on exact time when Abhi reached in lab?
Few more questions he has in his mind.

He went in Mumbai and first thing Kartik, Naira and Vaish did to check CCTV footage.

In CCTV they found. It was clear in CCTV someone intentionally did this chemical explosion to call it accident. A person with black mask did it. (Same like kiyu's if you remember)

But other thing which give them biggest shock is "Abhi jumped out of window to save himself."

Looking at this. Kartik, Naira and Vaish got shock. They quickly ran backside of college. To find Abhi lying there lifeless. Kartik went near him and touched him with shaking hands whereas, Naira and Vaish were scared. Tears were leaking from the eyes of three.

Kartik (with stammering): He.. he is.. he is breathing.

Words left from his mouth and he hug Abhi tight. Taking him in his embrace. Kartik broke down.

Vaish took baby steps and went near Abhi. She held his wrist and her hands were trembling.

Vaish (with happy tears): Kartik... we.. we need... to take... him... hos... hospital... His.. breathing rate is low.

They three quickly took him in hospital. Doctor did check up and everything necessary.

Dr: Patient slipped in coma. We started his treatment but don't know when he will get conciousness.

Dr explained a few things and left from there.

Vaish (mumbling): Theek ho jayega Abhi. Kuch nahin hoga usse. He will be fine.

Kartik heard her words. He hug her.

Kartik: Usko theek to hona hi hain. Nahin to main maruga bahut usko.
Naira: Main bhi. Mujhe bhi hath saaf karna hain. Or apne best friend ko maarne me jo maza hain vo or kahin kaha.

Vaish nodded with smile. Trio hug each other. A new hope they have with them.
