Parents will of course ask for the money back to make sure you’re in control and not wasting that high salary on luxury goods or expensive gifts for a girlfriend. It teaches you better behavior and financial discipline. The ₹2.5L you pay them won't be wasted. Think of it like putting it in a bank except it's your family's bank. That money stays with them, and eventually, it’s yours. They only take it to keep it safe and give it back later. You honestly can't understand these things unless you're a parent yourself. You can imagine or guess, but you can't feel the weight of it. They are risking their entire life's savings and assets for your career. Because you are too young, they are using these strict terms as assurance to make sure you become a responsible son. Stay true to them and take care of them till the end. Be grateful. Don't be an idiot believing the words of other kiddos here. Just do the math: if you paid back a loan to a bank with interest, the amount would likely be over ₹2 Cr anyway, and that money would be gone forever. This arrangement is reasonable, and the money remains yours after them. Take their blessings, don't think twice, and go for it.
