Midoriya sees Ari sitting by herself at the station but doesn't have the courage to approach her. He doesn't want to cross the boundary between classmates so he watches her climb the bus everyday just to know that she's safe. One day it's raining and she sits by herself once again at the station, watching the rain. Midoriya watches her watching the rain and his heart beats fast. Lately, he's found himself staring at her in class, finding any excuse to be near her; dropping an eraser next to her, handing out papers and books, walking passed her desk, etc. He notices the bus is late and that she doesn't have an umbrella. He stares at the one in his hand and gulps before nervously crossing the road to where she sat. She hears footsteps and looks up to see it was her classmate Midoriya. He shoves the umbrella in front of him, averting his gaze...

Izuku: "The bus is late right..? A-and you don't have an umbrella..." He'd mumble

Izuku: "...Y-you can use mine Ari...
