Hi there Eros!
I've seen quite a few of your pieces in the green room from this particular novel and thought I'd start from the beginning and see if I can make my way through a few of them!

Firstly, a few nitpicks:

I was doing my graduation in engineering in one of the top college of our state.

Apart from the games and sports

Apart from that,

Apart from that, there was one peculiar thing we always noticed. Wherever we went we would often hear some girls saying, "Look, the triplet of handsome and intelligent boys is here !!"

Hey, Eros!

That's right, I am exploring your works now. I enjoyed the read. You excel in prose too.
I liked the way it is written. I like the the quality of friendship you have created.

We were more like brothers from different mothers. They were very studious and devoted to their goals. The goals of the three of us were same, to get the best grades in engineering and achieve the trophy of student of the year, awarded to the first three toppers of the college.

"Look, the triplet of handsome and intelligent boys is here !!" And they would chuckle and giggle and smile at the blushing girl, whose crush was someone from our group.

We never gave a thought at that, until one afternoon, when an incident happened with me.
-
That afternoon, at about 2, George, Hunny and I were sitting in the library, completing the assignments together. The dead silence in the library was broken by the creaking of the glass door, followed by the tick tock of high heels. Nobody could resist and everyone's eyes rolled in that direction. There she was, Shanaya, the Miss Freshers of the college. She was indeed beautiful, but for me beauty didn't matter much, as I was focussed on studies that time. She came and sat at the table right beside me. I peeped through the corner of my spectacles and saw her reading a magazine that she carried.

paper under the sheet on which I was solving my assignment. I gasped. Before George or Hunny could notice anything, I quickly placed my palm on it.

After finishing the assignment, I asked George and Hunny to go ahead and wait for me, and also assured them that I will be back in a few minutes. I made up an excuse and stayed back in the library. I quickly removed that note.

Hello, shaniac here to review your piece!

I like the idea that you have presented here and the idea about starting off with the narrator excited about going into a college. I feel like this could relate to several people as college is just around the corner for some. That idea also gives me a bit of wondering if there will be something bad happening later on as the novel progresses. Even the title seems a bit suspenseful because usually when there's a note, something bad may happen. But, something good can come from it.

I like the description of the school. Though, aside from that, I kind of want more as to why the narrator feels as though he couldn't leave. I do realize that it may because of how the school looks and such but I feel like there is a bit more to the school. Also, ending of the sentence after the description feels unfinished. Maybe you could add a small thing that shows the narrator walking around the campus, enjoying the nice air.

I was doing my graduation in engineering in one of the top college of our state.

Alright, so you have a good idea. I like the setting: freshman in college, loving his new home, working hard to get that education he'd always dreamed of. However, I feel like you haven't developed him any further than that. It all seems a bit shallow. To make a really strong character, you should be able to answer questions such as: "What is his favorite color and why?", "Why does he want an engineering degree so badly?", "Where does he come from, what's his family like?", "Was he loved and nurtured as a child, or abandoned and left to fend for himself?". These types of questions may seem like way too much at first, but once you delve into who your character is and you as the author know everything there is to know about him, your audience will want to know more about him. Right now, he's just a 2D guy who doesn't even have a name to us (don't know if that was an intentional choice, or if you couldn't find a way to introduce him without it seeming awkward. If it's the latter, conversation is always a great way to introduce your character's name. Just have him talking with his friends, and one of them can casually drop his name so the reader has the main character's name without him having to awkwardly introduce himself through his inner monologue).

Next, I'd like to just point out that if you ever find yourself using the words "very", "really", or "so", you can probably find a better adjective to describe what you want. I would say it's fine to use those during dialogue, since they are after all college dudes and it's normal to talk using those words to place emphasis where you want, but in your writing you should always try to find more inventive ways to give emphasis where you need it.

There are also just a few parts that are worded weirdly. It almost sounds like you're going in a round-a-bout way saying something in order to just get more words in. I'll give an example.

"The incident engaged me into some other thoughts that distracted me from my goals of becoming a successful engineer and to achieve that trophy."

If you read it aloud, it sounds awkward. It would be better to keep it simple. A way to fix this particular example would be: "That incident was somehow able to distract me from my studies to becoming a successful engineer and achieving that trophy." Sometimes simple is better, but it really comes down to your decision as an author. My advice would be that if you think the sentence might be a little awkward, read it out loud. If you read it out loud, you can usually tell what needs to be changed.

Lastly, I would say add more emotion. Tell us how it makes your character feel, how his body is reacting. Is her nervous that this beautiful girl just gave him a note? Does it make his palms sweat and his heart race? Is he angry at himself for being so easily distracted? Does he feel bad for lying to his bros? If you use emotion, it makes your reader feel what your character is feeling. We are engaged in what is going on, and the emotion is what will make us really want to know what is in that note and read the next chapter. Stir our curiosity by showing us how curious your main character is to find out what's in the note!

So yeah! I honestly think you've got a great thing going, but it just needs more development and better word choice.
