When you are in love, you must be very happy. Such a signature can be written according to the mood at that time.

For example, if you meet the right person, you feel that life is meaningful.

For another example, the greatest happiness for the rest of my life is to be with you.

It can also be written like this: sometimes love will come later, but it will always come.

As long as you can express your feelings, there is nothing wrong with that sentence.
