I read to c20, and it was like this...
The king once visited the princess country and found her resembles his wife who just passed away. He planned to wait till her an adult then ask for marriage.
It's seem like the princess insisted on drinking the love potion on their 1st night and the king thought it was a posion the princess brought from home. The king was a gentleman, he thought the princess would rather kill herself, so the king took the potion and drank it instead. And so the potion worked and etc...

I like to think that considering the fact he would never lay his hands on her because of her age warmed my heart and I think when he fell for her with the love potion he worked up his affection to her eventually causing her to fall for him with his original gentle nature thus when the potion wore off they may have became a nice couple with a child (づ ̄ ³ ̄)づ
Girl is getting married off to a man in his SIXTIES and shes just a teenager. The love potion she asked for includes a strong aphrodisiac. This girl is a CHILD and shes gonna have to marry an old man, probably have a kid with him, and is desperate for anything that will make this less painful and disgusting for her.
I feel so bad. And this is just happening in the background of our cute, wholesome, fluffy romance with the main couple???? They made THIS the backdrop??
