I love you - To prepare you for that time when you want express your feelings to that special friend or family member. Often the subject of a sentence is omitted in Korean. This is the case here. In addition, the object is also omitted. Thus, you have a very efficient sentence. It sort of creates a mystical and obscure way to express love. It seems you could imply multiple meanings at once like, “You love me”, “I love you”, and just simply “love”.
