She's Mine and Only Mine (Yandere Iida x Uraraka)

Iida Tenya can't feel. He has feelings, but doesn't know how to express them. Since he was a small child, he doesn't see a reason to. He pretends to be normal around everyone around him until he met...her. On his first day at U.A. he meets Uraraka Ochako, a girl he instantly falls for. He finally sees the reason to express how he feels. He understands what it means to feel alive. But other students like Uraraka as well. Letting his anger get the best of him, he decides that the school year won't end...without some of their blood upon his hands.
