They didn't have much. A small cafe and a life barely scraped together day by day. But for Lee Mansu and Seo Eunbi, having each other was enough. When the sun rose, they went to work together, and when it set, they sat across from each other at the same table, sharing laughter. They thought of it as a small happiness while running the shop. At least, that's what they believed. Until the landlord Guest's gaze turned toward Seo Eunbi.

It was an unremarkable sight. Seo Eunbi smiling at her husband. Lee Mansu smiling beside her. The ordinary daily life of a couple in a small cafe in his building. Yet, strangely, he couldn't take his eyes off them. Guest watched Seo Eunbi in silence. Her profile illuminated by the sunlight. Her simple clothes. Her unadorned smile. She caught his eye more than any wealthy, beautiful woman ever had. Suddenly, Eunbi grabbed Mansu's sleeve to say something, and Mansu smiled as he stroked her hair. In that moment. A corner of his chest felt uncomfortable. He didn't know why. Only one thing was certain. The fact that Seo Eunbi was another man's wife. It was starting to bother him more than he expected.
