Bodyguard romance (R rated and M/M) - paramour

lee chanwook is an orphan that is in love with his childhood best friend and employer but thinks he is not worthy of his love and affection , while Rain is heir to a large empire and a model who is afraid of caring for someone too deeply RAIN i ran my hands through his hair the sunlight filtering from the windows highlighted his face and his every feature resembled fine brush strokes of a prodigious artist even the "blemishes"only added to his beauty . his shoulders where taut and his muscles tense as if even in sleep he was never at peace . laying my head down next to his i was overcome with a sense of possesion , this moment was mine and mine only and the thought of someone else laying here next to him made me see red and it scares me that i think that he is 'mine' because i always lose whats 'mine' and he is something i cannot afford to lose LEE CHANWOOK if all things beautiful and flawed were put into a person it would be rain he infuriates the living shit out of me but nonetheless i love every aspect of him , i always have. (ps- i know the writing style may seem kinda morbid and intense at first but gonna make it more lighthearted and enjoyable as the story progresses)
