Pia Sahastrabuddhe was the youngest daughter of the college director. She was the one that pursued to be a doctor from her dad Viru Sahastrabuddhe. She showed strong fondness and passion for Ranchoddas Shamaldas Chanchad while also being engaged to a manipulative, materialistic husband Suhas Tandon.
Rancho initially met her in a wedding he (and the other two 'idiots') broke into in attempt to get 'free food', after overhearing Suhas accusing Pia for wearing her "ugly eighteenth century watch". In response, Rancho approached Pia and immediately dissuaded her from marrying him (an "ass"). She initially disapproved the advice, but Rancho supported it by means of pouring "chutnee" (mint sauce) over his expensive leather shoes, to prove to Pia that he was just a 'price tag' who would openly declare the price of his products, and that he would unfairly put the idea of expensive brands and products onto her. Pia eventually appreciated Rancho's demo and suggested that he explains it to her dad (who to Rancho's dismay, was the director Viru Sahastrabuddhe [Virus] himself). Virus having caught the three idiots Farhan, Raju and Rancho broken into this wedding (Pia's sister Mona Sahastrabuddhe), Rancho claimed that he was designing and constructing an inverter to help keep lights on even during a power cut so that wedding celebrations like his would not be disrupted. However the design was not on their hands at the moment and Virus disbelieved them.
Pia was shown again after Suhas purchased her a luxury limited edition watch. Initially, Pia thanked him, with the assumption that her husband bought that watch as a kind gesture. Soon, she approached Rancho in Fury asking him if he changed Chatur Ramalingam 's speech (the modified version contained inappropriate statements about her dad). Rancho tried to convince her she did not have a problem with her dad but unfortunately said so at the same time as he presented his new inverter (which was labelled "VIRUS Inverter"- a mockery to Viru Sahastrabuddhe 's name). Pia, not appreciating Rancho disrespecting her dad broke the inverter and this forced Rancho to work hard later to rebuild it. The conversation however transitioned to a talk about Suhas again- Rancho claimed he was not actually interested in her. Pia initially disbelieved (considering that she felt touched at Suhas' gesture of buying her a watch). But Rancho proved that even that act was simply a materialistic act, after he confiscated that watch and tricked Suhas into thinking Pia lost it. Suhas once again showed his 'price tag' tendencies and felt enraged, coercing Pia to find it as soon as possible so she does not have to wear her 'eighteenth century piece of junk' at dinner. Pia felt crushed by that possessive behavior, took the watch back from Rancho and returned it to Suhas, blatantly calling him an "ass". The conversation continued and Rancho even convinced Pia that she never actually loved him in the first place. In response, Pia and Rancho started spending more time with each other. Pia also got to know Rancho's friends for the first time after she was forcefully called to assist with a medical emergency of Raju's father. Pia was captivated by Rancho's kindness and compassion for his friends, and they gradually fell in love after spending more time and interacting with each other. The song Zoobi Doobi highlights their true love- featuring both of them in captivating fantasy worlds; the world standing still and Rancho flying to Pia, Rancho being a weatherman on TV fictionalizing rainy weather for romantic couples, and both of them witnessing a gigantic moon.
Pia continued to be the fourth friend throughout the rest of the movie- she assisted with another medical emergency in response to Raju's attempted suicide: Bleeding, being in a coma and experiencing shock after waking up. She even asserted against her own fathers attempts to manipulate the exam papers to stop Farhan, Raju and Rancho from graduating- even giving them the keys to Virus' office allowing them to steal the papers. Virus unfortunately caught them when Virus had Pia's phone on front of him while Rancho called her by Virus' office number. This created suspicion and after Virus caught them, he rusticated the three idiots. Pia confronted her father, openly admitting that she provided the key, and asserting the unfairness of his behavior, even recounting their heart-wrenching moment of his son's 'murder'.
Rancho continued to show his true worth by reciprocating Pia's assistance during emergencies; using his engineering knowledge to help her sister Mona deliver her baby during a heavy rainstorm when they could not access a hospital.
Present Times[]
Despite Pia's past affairs with Rancho after finding her ex-fiance Suhas an asshole, it turned out that Pia was yet again engaged to Suhas, in fact presently getting ready for her wedding. Farhan and Raju planned to do their part (like Rancho had earlier) to stop her from marrying him. They did so by dressing up as wedding guests (similar to what they did in the older sister Mona's wedding years ago). However, Pia refused this time, and was convinced that Suhas has changed from the asshole she remembered him to be earlier. Raju had disguised himself as a servant, and had falsely accused another servant for "being too slow". This allowed Raju to perform housekeeping duties, such as ironing Suhas' coat. Raju had dipped the iron over chutnee (mint sauce) and applied it to Suhas' expensive coat (which he planned to wear for the wedding), creating a large, almost permanent stain. This ended up proving Suhas' past 'insufferable' personality: reacting aggressively to the mint stain and referencing the 'high' price of his coat in front of Pia. Raju had escaped downstairs, with a false promise that he would return the coat in a clean state. Pia felt taken aback, but was still convinced on marrying Suhas, with a different view that it would be "too late" to change her mind.
When Pia went down to the altar, Raju concealed his face and followed her, continuing to dissuade Pia from marrying Suhas. Although Pia felt it was too late, Raju still convinced her that she would regret it later if she continued the marriage given Rancho was around. Meanwhile, Suhas desperately asked another servant upstairs for where "housekeeping" (Raju) was, given his earlier promise to clean and return the mint-sauce stained coat. The other servant was suspicious about Suhas' presence upstairs as he had found 'someone' down at the altar (which should have been Suhas, but was instead Raju). Down at the altar, Pia was still embarrassed at Raju's idea of escaping the wedding. Therefore, Raju confidentally revealed himself to the crowd in attempt to embarrass Pia, and to convince her that people will forget about the situation. As a result, Virus was once again taken aback at Raju's presence, perhaps remembering the last time he and his friends had barged into his daughters wedding. Suhas had then followed on downstairs and found out that it was "housekeeping" (Raju) down at the altar. Having been caught by both of them, Pia finally agreed to hold Raju's hand and flee from the wedding with him towards Farhan's car, where they continued their journey to find Rancho. Virus and the crowd observed the situation in dismay, and forced the ceremony music to a halt. In the car, Farhan had mentioned about his uncertainty of Rancho's marital status, putting Pia in panic after the trouble she had taken to flee from Suhas' wedding.
Ending[]
Pia was the first to reunite with Rancho in the sandbar. She had initially slapped Rancho (who had repeated his confessions from 10 years ago) due to him not telling her he left. However once that recovered, Rancho and Pia shared their kiss after years, also thinking about life after they marry. Pia agreed to marry Rancho, yet was disgusted by the idea of changing her name after marriage, even after figuring out Rancho was actually "Phunsukh Wangdu".
The film ended with her running away from Chatur with the gang.
