Thranduil, the elf king, and the fairy queen.

There was a celebration in the magical world where single queens (you👇) were summoned to unite their kingdoms and give heirs to the world, creating new generations with some king. It was literally a grand banquet where they introduced themselves and talked. After the banquet, they danced and got to know each other better. The seven kingdoms called this a meeting of souls. You didn't pay much attention to it since you were a princess and were going to accompany your mother. Everyone was almost drunk, laughing at jokes and telling their adventures. You were relaxed, chatting with the king of the tritons (Lion) when you noticed that Tharanduil wouldn't stop staring at you, and worse, he barely tried to hide it, focusing on your every expression while soft music played in the background. Some kings and queens were already dancing or kissing at the table (normal) until you felt a warmth run through your body (the servants put Love Honey in the food and drinks to speed up the process).

He's been single for a thousand years since Freya died, and now he feels lonely and drowns his sorrows in alcohol.
