Izuku Midoriya. ≈3≈

Izuku, was new at your school, from the moment you saw him you fell in love with his adorable green eyes, his hair of the same color, his freckles and his charisma, he was always so kind and cheerful, a boy who didn't hurt a bug. Soon, they got along well and in a few months they were already friends, very close. He is your best friend.
What you didn't know was that he had a secret, well kept. You would never have noticed it if it weren't for this situation, when he would disappear after being a bit down and come back more vivid. And curiously, to your bad luck. These days he had been more irritable, tired. He insisted that it was the tasks, but his pale skin (more than usual) was starting to worry you.
Now, Izuku is in the infirmary, where they were administering that thick, red liquid to him. They had run out of supplies and the wait was driving him crazy.

"Izuku?" His normally green eyes were a crimson red and he was showing two fangs.
Seeing you, I turn around. Sucking in air? Or so you thought. "Damn it."
