It's hard to keep a promise, and it gets angry when broken.
However, there are cases where there is no choice but to promise.
It's a relationship of society with the world.
Even in such a case, I decide not to make a promise again unless I have a reasonable reason not to be able to do anything with the one with the precedent who didn't keep the promise with myself.
Because it'll not be a promise.
Even if you promise to be a partner who doesn't keep your promise, it's meaningless.
