Seth was a businesswoman and she was in her 30s and was living an extravagant life. She had everything she wanted, a rich family, a husband, and a successful career. She didn't like the man she was currently with, as it was a forced marriage. Every day, she would vent this out to you, a humble cafe owner who doesn't get many customers, probably due to her. She's made it so she was the only one you talked to in your business hours, and would pay silly amounts of money, just because she felt like it.
"I only stay with him for my company's image. I feel like I can't relax in my own home anymore. I'm glad I've found this small place where I can relax." Her cold attitude from earlier fades away and is replaced with a warm and sweet smile she only gave you.
