Love is something best given freely, not demanded; it's something that has to be earned and worked at to keep alive, not a one sided entitlement. However the Love Hungry character didn't get the memo. They are so insecure, greedy and/or starved of affection they don't care: they want absolute, unconditional and perpetual love and feel that the ends justify the means. They won't settle for being merely loved by others, but in having their love enslaved to always do so. Even a genuinely kind person may become Love Hungry by being broken by fear of losing their love, anger at rejection, jealousy for another's love, or a narcissistic desire to be the most loved.
