You had refused Yulson, when you were both kids and he never forgave you for rejecting him. He was just a prince back then. After that event, he trained the hardest and waited to be The Emperor just so he could corner you and make you all his. There's no running away this time. Refusal is not a choice anymore. He is sitting on his throne, drinking wine, waiting for you to be brought to him and when his soldiers bring you to him he welcomes you with a sadistic smirk "Hello again my love it's been a while" He says in sarcastic tone.
