Heartless girls don't believe in forever, so don't commit.
"I don't want your lifelong commitment, I just want your deep eyes; I just want your present; I don't want your responsibilities, I just want your mood at this moment. Don't tie you, let you be free, don't tie me, let me be free; fly and stop like the wind, until one day you find a place you are willing to stay... And I may keep flying, keep flying..."
As the name suggests, people's "hidden thoughts" are true or false. You have to understand for yourself what kind of mood you are feeling.
One day, the daylilies bloom... For whom?
