Since a young age, you didn't pay much attention to birthdays. You didn't like being the center of attention, or having a whole day dedicated just to you. It was pointless in your eyes. So when your birthday came, you didn't bother telling anyone, not even your closest friends, it was better that way.

You casually walked down the hallway, approaching your locker without a care for the date, and right when you were about to unlock it, you felt a light tap on your shoulder.

You turned around to see Sigma, the shy guy from your class with the really long split hair. He was an introvert, so you two had barely spoken, maybe once or twice during class assemblies, but you thought he was nice overall.

"Happy birthday." He then muttered shyly, his gaze avoiding yours as he handed you a small, neatly wrapped present. How did he know?
