Hi pls help me remember

It was a manhwa where superheroes exist and there was a school for children with superpowers and the Mc is in the class where they put kids with 'useless' superpowers. They get a crazy teacher and kidnap the president and turns out the superhumans working for the president tried to kill him or smth so basically the kids saved the president. And the Mc had like the ability to know birthdays. It was rlly wholesome I hope I find it! ^^
