Nensu let out a soft squeak, once she felt the notion of Midoriya pulling her closer. The female teen brought her left hand from his back, and gently set it on the side of his face, stroking it in a very comforting way with her thumb. Even when they remained in this state, Nensu had to admit that this was perhaps the most wholesome she had ever felt; the last time, having to be until her mother was departed to the hospital. 
The feeling was enough to nearly make her cry again, but then, she had felt herself in the most secure state, while having to be in embrace. In terms of romance, Midoriya had officially become her first significant other; with her, having to be the same for him, she had to guess. 
They were both nervous, admittedly, but for their teamwork, she had to believe that they may just be able to make this work, as they were now on the right track.
