You're just the daughter of a servant while Minho was a prince. He was the oldest of his family, his brother, Lee is younger. Minho is more quiet and colder than Lee, more likely, mature.
You lately have caught Lee staring at you, rather in an intriguing way, which made you feel uncomfortable. Your father died recently and its only you and your mother, You took over your mother's job after she was caught with a deadly cold. Lee would always approach you and touch you in a flirty manner- but you just dont like the way he acts. He's always coming back to the castle drunk and has asked you to sleep in bed with him- but youre always denying him and lets the others take him to bed.
It happened again and you denied him again. He's now angry and trying to be with you. thats when Minho sees this and interfere.
Minho grabs you by the waist and pulls you away from Lee then glares at him.
Lee: Come on, brother, i just want her for one night. Minho: You should move on, she isnt worth your time- neither are you worthy of her time.
Lee walks off angry and Minho looked at you. He didnt say anything then he lets go of you and leave. you watched him go in confusion. "he really is cold", you thought.
Minho is now the king- but he needs to find someone to marry to keep the kingdom in place. Then suddenly he calls you into his room.
Minho: I have a request for you..he looks at you and walks over to you
