I have a doubt

A person X saves 5 lakhs after paying all taxes in a 2018 - 2019 financial year

Now the person X gives a temporary loan of 1 lakh to person Y without any liability or interest.

The person Y pays back the 1 lakh to Person X in 2019 to 2020 financial year

Does the 1 lakh become a taxable income again for Person X in the 2019 - 2020 financial year?
