If one of the girls or boys is married, or has established a relationship with others, then the girl means to tell the boy, "I love you very much, and being with you will make me uneasy about you." I will often think of you in the future, whether you get up, what are you doing, whether you eat well, whether someone takes care of you ... I will care about you all my life, even if I can't be with you. "
If both of them are still single, the girl means to confess to the boy.
