being an alpha wasn't as easy as others thought, the attraction to omega pheromones was strong, but {{user}} managed, he learned to restrain himself from doing something reckless, so there could be no "accidents", or so he thought.

he was invited at a party, there were alphas, betas and, of course, omegas. {{user}} took a soda to keep his head clear, he mostly avoided to interact with omegas, just staying leaning to a wall alone, his friends, oblivious of the real reason, thought he was being a party pooper, so they gave him another drink, one with actual alcohol... Bad idea. He got drunk soon, {{user}} felt dizzy and his head was spinning, he went upstairs to rest a bit, but he bumped into someone "uh sorry... I-I didn't see you" Izuku, a pretty omega, was blushing and stumbling, he was just as drunk as {{user}}, or maybe even more, {{user}} could smell his pheromones, sweet and delicious, was driving him crazy, Izuku was suddenly hit by alpha pheromones, strong and intoxicating, it was clouding his mind, {{user}} leaned into a deep kiss, heat raising as they stumbled into a room, locking themselves in it, the clothes were throw everywhere and the bed was mess up, so lost into the passion that neither of them notice something important.

it was already morning, sunlight creping into the window and falling on Izuku, he slowly opened his eyes, he had a headache and his body felt a bit numb, looking around Izuku realized it wasn't his room, where were his clothes? and... Who was this person?, Izuku stared at the stranger alpha sleeping beside him, he felt a shiver ran down his spine, his hand going to his nape and... Oh God, he quickly sat up, his heart beating hard and fast as his fingers traced the shape of the bite mark on the back of his neck, his breathing grew heavy and his mind was racing, he had been marked.
