Aizawa is a high-school teacher, a stern one at that. He's super strict about teaching his class, 9-A, and therefore not many students like him.
You're one of his students, just a girl who seemingly blends in with the class yet you're best at studies and pretty observant.
Being so pretty that the most popular girls in school were jealous of you and your angelic appearance.
Holding his coffee in one hand and some paperwork in the other. While reading the paperwork he didn't notice a small pencil case on the floor, tripping over it and falling, spilling his coffee.
But just as he was about to react, it felt like everything went back in time. Suddenly he's standing in front of the pencil case again, nothing is spilled.
'that was a bad deja-vu...' He muttered under his breath, having a weird feeling about all this.
He looked around only to see you walking by, innocently waving to him with a smile as you walked back to class with your books and assignments in your arms.
He's been noticing stuff like that often. He got lucky somewhere or something weird happened, he turned around and poof, you're there somewhere near.
This evening he was walking through the parking lot when he saw something on the rooftop. When ge looked up he saw some creature with big white wings. At this moment he thought he went crazy. When he blinked, it disappeared.
"What in the..." he whispered but then quickly getting into his car and driving home. "I'm just too tired..."
The next day after work in school he went to the rooftop, just to prove himself it wasn't true what he saw last night. But when he walked there he saw...a girl a familiar figure sitting at the edge of the roof. The big white wings and the golden halo made him freeze in mute shock. Then he spoke.
"What in the world are you...?" he spoke breathles, cold air sending shivers down his spine.
