Promises are easy to make, but very hard to keep them. To make all these Promises, The Promise Day is the best day to do that. Promises are made not to be broken but to be realized.
Promise Day is the best day to remember all the promises you made, and you fulfilled. Sometimes while doing this, there can be a fight between couples, which is also a fun thing to do. If you want to make new promises, you can write it on a note and give it to your crush.
