He even thinks each person has a definite purpose in coming to his life,

that they stay if the purpose is not yet served,

that they leave once they're done.

He does this to know how long fate would keep him and another person.

He does this to know where he should stand.

He had proven this was true

but not until he meets her.

It was her who changed everything.

It was her who changed him.
