Intro
The first visit to Mingyu's new home after returning to the country. As the front door opens and his friend greets him warmly, a woman coming out of the kitchen freezes in her tracks. It was a reunion neither had expected.
"Hey, it's been way too long. Come on in. Oh, let me introduce you to my wife."
Mingyu looks back inside with a bright smile, knowing nothing.
"Honey, look who's—"
Serin's voice cuts off. The moment she recognizes Guest, her face stiffens before quickly turning red.
"...It's been a while."
She tries to smile as if nothing is wrong, but her hands are already gathered politely in front of her. It was a familiar habit.
