Idhayam Murali

The film opens the night before a big wedding, where everyone is dancing and having fun. A married couple expresses their concern that the groom has still not arrived, to which a middle-aged man assures them that he will be at the wedding hall the very next morning.

In New York, on a bright and colorful morning, a group of friends are lazily sleeping on a couple of couches in a large house. As the phone keeps ringing and one of the friends picks it up, the same middle-aged man from the wedding frustratedly pleads everyone to arrive. The friends all get up and look around the house for a young man named Idhaya, only to open the door to a bedroom and see that he is tying his shoes, ready to leave.

Idhaya and his friends quickly hop on the next flight to India, where Idhaya accidentally switches phones with a charismatic stranger and begins narrating his life story to him:

The year is 1998 and Idhaya, as well as his two best friends Khaja and Prabhu, are children studying in primary school. Khaja and Prabhu's habit of playing jokes on Idhaya, such as telling him that kissing leads to pregnancy, causes Idhaya to unknowingly feel responsible for when his favorite teacher, Geetha Miss, becomes pregnant. Over the course of her pregnancy, Idhaya develops a crush for her, eventually leading to him and his friends rushing her to the hospital to have her baby. Idhaya leaves without telling Geetha anything, marking his first one-sided crush.

Idhaya's story flashes forward to 2006, where he is now in high school. Khaja and Prabhu jealously note that after school each and every day day, Idhaya gets on the bike of a rugged looking upperclassman named Juju, and after weeks of this repeatedly happening, Idhaya finally tells them that he does this in order to see Samantha, a girl from Idhaya's tennis class that he has a crush on. Eventually, Idhaya, Juju, Khaja, and Prabhu all join the same after-school tuition center as Sam, and they visit her school for a quick charity donation event, Sam invites all of them to her house for her birthday party. Upon arrival, Idhaya and his friends start to notice that Sam does many things twice, such as giving them juice to drink. When it's time for Sam to cut the cake, Idhaya comes to the painful realization that Samantha has a twin sister named Samyuktha, and that while one of them goes to Idhaya's tuition center, the other goes to his tennis class. Upon learning that the sisters frequently switch places with each other, Idhaya is so heartbroken that he can no longer confess his love to Sam. Feeling guilty and shallow for not knowing which of the sisters he truly loved, Idhaya leaves the party without giving Sam the heartfelt gift he had brought to confess his love to Sam with.

Idhaya picks up the next part of his story in 2011, where he is currently a college student. As a brutal fight ensues while multiple households come together to watch the 2011 Cricket World Cup finals on Idhaya's rooftop, Idhaya gets injured and has to go to the hospital. There, he meets Sachin, another one of his, Khaja, and Prabhu's upperclassmen from primary school (who currently works as a doctor in the same hospital Idhaya gets admitted to), Lado, another doctor at the hospital and Sachin's girlfriend, as well as Amudha, the doctor that actually operates on an injured Idhaya. Idhaya immediately falls head over heels for Amudha, and after some shenanigans, ends up bonding with her when she comes to spend the night at his house. Idhaya's friends quickly become friends with the doctors and they all spend time with each other, travel together, and enjoy their lives to the fullest. Soon, it becomes time for Amudha to move away in order to follow her career. The friends all meet up with her one last time at the train station, before she moves away. Not wanting to let go of her the way he did with Sam, Idhaya slowly tries to work up the courage to tell her how he feels, walking up to the train with her, and staying with her even as she boards it. As Idhaya's nervousness and stress continue to build up, he eventually doesn't have the guts to tell Amudha how much he loves her, letting her walk out of his life and sincerely wishing he was more brave.
