Considering that her eyes were closed, Nensu was oblivious to the other teen’s attempt to get closer. In fact, she turned her body to the side to make a cute expression, as well as to hide the blush that was appearing on her face. If she was even aware, Midoriya could, very well, have ended up falling forward onto the floor. By the time he spoke, was when the teenage girl was able to really show some awareness. While he looked for his wallet, Nensu was able to walk upon him from behind, and hug him; wrapping her arms around his form, press the front of her body against his back, and rest her cheek on his shoulder. 

Momo wasn’t even aware of Hiems trying to reach for her attention, since her attention was diverted towards the young couple, who stood only a few feet away from them. Funny enough, they didn’t even come to notice them even standing there, watching. 
“It’s still sweet to watch”
The raven-haired teen internally squealed, although she did take a glance at the taller boy next to her, having to wonder whether if they could do the same thing.
