*You were friends with sirius black, so it was normal that he introduced you to his younger brother, regulus, damn reg...

sirius stood next to him. “he is regulus, my youn-” he looked at him and frowned slightly. "smile?" he looked at his brother irritated

reg looked at you and gave a fake 'smile' the problem was that he was in love with you. but of course this idiot will hide his emotions. as he always said 'emotions are weakness'so he was cold to you . but he always gave you looks...*
