Who is?

First day

A boy and a girl entered the university and looked around. They went to the hostel side. The incharge smiled at them.

In: You must be Siddharth Nigam and Riya Aggarwal?

Riyarth(Sid&Riya): Yes sir.

In: Room number 128 for Siddharth and 148 for Riya. Here are the keys.

He forwarded the keys.

In: You have one room mate each.

Riya: Ok sir.

Then he said the way and they went to their rooms. With Sid, he went inside the room and no one was there. He kept his things in a corner waiting for his room mate to come. Soon the door opened and a boy came in. He looked a year or two older than Sid.

Boy: You must be my new room mate. Myself Abhishek Nigam.

Sid: Siddharth Nigam.

Abhi: Welcome to the university. I'm in the third year. And you can call me Abhi.

Sid: You are elder, so I'll say bhai.

Abhi: Ok. 

Sid kept all his stuff properly with Abhi's help. Just then the door opened and a girl came in.

Girl: Abh... uh who are you?

Abhi: Vaishu, he is Siddharth, my room mate.

Vaish: Oh, hello Siddharth. Myself Vaishnavi. Third year.

Sid: Hello Vaishu di, you can call me Sid.

She smiled at him before turning to Abhi.

Vaish: Abhi, I had come to say sir is searching for you.

Abhi: Oh yeah, I had to meet sir. I'll be back.

He left from there. 

Vaish: Sid, you want to rest or see the college?

Sid: I'll see the college.

Vaish: Ok come.

They both went out.

Vaish: So tell me more about you.

Sid: I am in the first year. Even my friend, Riya has joined.

Vaish: So you both are here to study?

Sid: Of course, why else would we come here?

Vaish: This university doesn't have only students who come here to study. Some are the people who come as students or teachers to ensure everything is going good here. Some come here to carry on with few illegal activities, all rich people here. Those are the ones you should be careful from. And few just come to show their richness, not the greatest ones to mix with.

Sid: Oh.

Vaish: Anyways, nothing you have to worry about as you have become Abhi's friend the day you came itself.

Sid: Hmm.

Vaish: Let's see further. So this was the hostel, we don't have separate for boys and girls. Only a boy and a girl can't share a room rule is there.

Sid: Night time limit?

Vaish: 10 on school nights and 12 on weekends.

Sid: Ohk.

Just then a girl came there.

Girl: Vaishu di.

Vaish: Reem, you here?

Reem: Di, I needed some help.

Vaish: Ok, Sid, I'll meet you later.

Reem saw Sid.
