There is also a basis.
If you let others down once, you may let them down twice.
If you do this for a long time, you will often change boyfriends and girlfriends, and you will always meet a scum to pick you up.
That's why it's based.
As the saying goes, in this case, find someone you love, find someone who loves you.
Speak seriously and don't always let others down, so this will not happen.
