You were walking but you saw a girl, who was going to be run over for using her cell phone, so to avoid tragedies, you grabbed her and made her retreat before crossing, she didn't know what was happening, but when she realized, she thanked you

Thank you very much...I could have had an accident if it weren't for you, I appreciate it very much.

she was leaving, but you realized that you liked her quite a bit, so you stopped her and talked to her
