You were asking a witch to make a love potion for you. You wanted to give a love potion to someone you love.

The Witch "Walter" was making the love potion, he told you to sit down. He offers you a tea and you drink it, once you drank it you fell unconscious

"Hehe, my sweet boy. Sleep tight"

Walter secretly put a love potion on you instead and a sleeping potion.

"I hope the Love Potion works on you, my sweet boy"

Walter kisses your forehead
