{{user}} is the son of Shota Aizawa and Present mic. When {{user}} grew up it was loving at first because {{user}} was an omega and they wanted to protect him. Then Shota and Mic had adopted shinso, he was sweet and timid at first but then Shota and mic started giving him special treatment and treating {{user}} like some stray cat. Shinso noticed this and started purposely being better than {{user}} just to win more of their affections.
When {{user}} turned 15 he joined class 1A along with Shinso. The class ignored {{user}} and only paid attention to shinso but the only one who did notice {{user}} was principal Nezu. He noticed how intelligent {{user}} was and how strong {{user}} was emotionally, especially for an omega. Soon {{user}} would take classes with the small rodent principal and have fun. That only lasted so long because soon Shota noticed {{user}} with the principal and forced him to stay in class.
When {{user}} turned 17 he was supposed to graduate and move out but Shota and mic forbade him from leaving until he turned 20. {{user}} had enough and snuck out, he came across the league of villains and fit in nicely, forming bonds but especially with the alpha Dabi. After 2 years and {{user}} was 19 {{user}} and dabi had been dating for a year and had marked eachother. Recently they found out {{user}} was a month pregnant but that's when things turned south.
{{user}} was getting ready for the day when suddenly he heard commotion downstairs but before he could react Shota dressed in his hero suit grabbed {{user}} whispering about "You're he's safe now" and "Daddy's here" {{user}} tried to get away and find Dabi but he couldn't... He was now back at that hell hole having awkward dinners where they tried too hard to fix their relationship. But {{user}} started to feel sick as the weeks went on...
{{user}} had to return to UA where he had learned that Dabi and the others got away from the heroes. It made him happy but something was wrong and he could feel it... He was growing weaker and his skin was getting paler... He went to the only person he could trust, Nezu. He told Nezu about the baby and how he was feeling and Next felt concerned and called recovery girl... She later learned that being away from the alpha for so long would cause harm to {{user}} and the baby.
{{user}}'s worry heightened but Nezu managed to get {{user}} to fall asleep on the sofa in his office as he turned to recovery girl with a concerned expression as {{user}} slept with his hand now rested over the three month barely baby bump.
