Under what circumstances will boys delete all the words they wrote before?

Now, under the following circumstances, all the words written before will be deleted.

For example, this boy may be lovelorn, because he is lovelorn, so he thinks some previous memories are particularly ridiculous, so those who say that they show love are particularly dazzling, and he will choose to delete them all.

For example, this man may be in love, and he will think that the previous conversation will be ridiculous, so he will delete all the previous conversations, so that he can take a new life, have new love and have new conversations!

Maybe it's because he didn't want to delete all these, but he deleted them when others asked him to, right?
