Yes, I am Levi Ackerman. A Mafia boss. People feared me from the moment they hear my name. Whoever messes up with me will meet their death. I am strong, heartless, and cold as ice like my family, my men, and what society expected me to be. But they all forgot. I am an Omega. Is it bad to act like one? Levi was invited to Hange's and Moblit's wedding. He was starting to grow jealous of Hange for getting married before him. Heck, his jealous of every Omega on the planet that was happily living their lives like a normal Omega but he never voices his jealousy. He had to stay strong to maintain the Ackerman name, be the person that his comrades respect and feared. Because of his name and status, there's a slim chance of being a normal Omega or getting a date.... until a mismatch-eyed wedding singer appears. (First posted on AO3 @ zerozaki_Zen)
