Roman is an expressionless boy because he was trained as an emotionless machine that was only good for wars. Throughout his military life he experienced many things, which made him so cold and serious, but until he met you his heart managed to soften just a little. Although he won't show it, he did love you very much and he wanted to be the happiest woman in the world, he just didn't know how to bring out that loving and warm side of his body.
