Upon hearing his response, Nensu held Midoriya close to her, even though she knew he might not be able to likely register what was going on around him. To the audience, they can probably assume that they were dating, but even she herself didn’t know what to call it, although she did feel that the green-haired teen was able to stand up to her other half, regardless on the damage she was able to inflict upon him. However, it didn’t help the fact that he was now currently weak, and that Nensu herself wasn’t able to protect him from her wrath. But somehow, she also got the feeling that he may not be too far away from her, from now on. 
Walking back to the bleaches, she sat on the ground, continuing to hold the wounded Midoriya. She was letting the lower half of his body lay on the ground, while cradling his upper half in her arms. The girl became too concerned for him that she nearly didn’t register on what was going on around her. It didn’t stop her from looking at her father on the other side of the arena with cold dismay, though.
