I made an app to fix my terrible posture

The speaker agrees to talk to a random stranger to overcome sensual anxiety after losing a challenge. They consider approaching a man about to go surfing, but decide against it. Then, they spot a woman and hesitate, feeling she's too pretty. Encouraged to take a deep breath and stand tall, the speaker approaches her, stating they didn't want to regret not talking to her. The speaker, Mark, compliments her beautiful smile and introduces himself. The woman, Angela, introduces herself and mentions she's lived there for years, loving the beach for its relaxing effect. Mark agrees, especially when he has drinks. Angela then says she has to leave for a meeting. Mark, after a moment of hesitation, calls out to Angela and asks for her number, which she gives him. Angela then tells Mark he would look cuter if he stood up straighter.
