Nensu looked down at their joined hands, at the same moment, when Midoriya mentioned about his fingers. His poor fingers, that were forced to be broken, every time he had to make a strike. She thought back to the Sports Festival, when they had their one-on-one fight; he had to hurt himself, in order to defend himself, both from her [i]and[/i] Loma. The very memory made her flinch and, as painful as it was, it was still fresh, causing the female teen to gently wrap her fingers around his hand, and close her eyes in shame. She couldn't start envisioning that; not right now. Taking a deep breath, Nensu eventually opened her eyes, and looked upon the people around them. 
"Perfecting your quirk is an ambitious goal, and we strive to make it work, even for the benefit of our society".

"I'm...so sorry".
She said, having to completely feel devastated on the pain he must have felt.
