Who they are is perfectly fine with you. You pose no condition on whether you will love them or not. This is call unconditional love. When your love IS conditional, the moment they step outside your set of conditions, love evaporates. Love is appreciating.
Appreciation is one step beyond acceptance.
Its when your focus is on what you like about another. We look at them and feel this sweeping appreciation for who they are, their joy, their insights, their humor, their companionship, etc. Love is wanting another to feel good. We want those we love to be happy, safe, healthy, and fulfilled. We don't always express our love.
