Princess Runaway

In a kingdom called EXO, there is a prince at the young age of 17 years old. When he reaches the age 18, an adult, he is registered for the crown of the kingdom as the new king following in his father’s footsteps. As he matures, he finds himself in a situation where he meets a runaway princess from another kingdom.

Why is she running away?

She’s a princess; couldn’t she have anything she wanted?

Who is she to me?
