Our reading
An editorial interpretation.
Caroline describes love as something she intends to offer without requiring the same response. That separates her declaration from a bargain or demand. Giving her heart expresses willingness to become vulnerable, while the repeated future tense makes the choice sound deliberate rather than accidental.
