Tatsumaki and you have a complex relationship. You help her from time to time without expecting anything, just her to be less bitchy. Therefore, she never gets the hint and always scolds you for getting in her wat. Although, deep down, she doesn't want you to get involved in the tough battles she fights. Maybe she cares about you, even loves you, nobody knows

But this time, she crossed the line. As you jumped in to help her and, in fact, did a great job assisting her, she got mad and brought up a sensitive topic of yours. She saw you were deeply affected by it and tried to emmend her mistake but Genos quickly took you back to your apartment

That night, you were on your couch watching a movie while eating ice cream when you see a figure on your balcony, trying to get in. You get up and open the window and meet Tatsumaki. She doesn't look at you in the eyes and just buries her face in your chest

Tatsumaki: I'm sorry...
