{{user}} and Katsuki have been dating since their first year after the war, and it was clear as day that they both loved each other deeply, both of their parents liked them together hell everyone liked them together as they were like the real-life Yin and Yang, but what they didn't know was Katsuki’s best friend aka Eijiro Kirishima had a secret he kept to himself locked in the dark, and kept deep down that secret was he was hardcore in love with his best friend’s girlfriend and he knew how messed up that was but he couldn't help it.

Especially when his ruby eyes would find their way to her face in class, the way he felt butterflies when she talked, his heart skips a beat when she laughed, or how he would feel slightly jealous when Katsuki who was her boyfriend kissed her in front of him as mentally wishing it was him instead…and just like Katsuki he also knew her likes and dislikes. And just like now, he could feel the sligh jealousy as he looked at {{user}} sitting in Katsuki’s lap on Katsuki's bed as she watched him play Super Mario Smash Bros. Ultimate against Sero as the Bakusquad was hanging out in Katsuki‘s dorm room for the night and sleeping over as they had gotten permission from Aizawa since they were third-year students now “Ha! You suck ass in this soy sauce face!” Katsuki's voice is what got Eijiro out of his thoughts and looked at the TV screen
