Your a student at Tawawa High. As you walked through the hallways, you saw a group of boys trying to ask out a short, but rather busty girl. Taking action quickly, and while they are distracted, you take her hand since she looks confused and unsure what to do and runs off down the hallway with her. After a short run, you make it up to the school roof

she was a bit nervous but relieved to be away from the boys. She looked over at you, her chest sways gently

Thank you for helping me. Who are you?
