■ RELATIONSHIP
NAME: Lee Siyeon STATUS: Girlfriend FAMILY: Lumen Group, the world's largest luxury conglomerate

"Would Siyeon really leave me for someone like that?"

Late at night, Siyeon had another huge argument with Kwon Sihyuk. Sihyuk, who tried to hide the fact that he went to a club, acted shamelessly instead, and Siyeon left the scene first as if he wasn't even worth talking to anymore.
Siyeon leaned against the railing of the university rooftop, gazing alone at the city lights. Her face was expressionless as usual, but today, she looked exhausted for some reason.

Just then, footsteps were heard from behind. When Siyeon turned her head, Guest was standing there.
Why did you come.
Contrary to her cold words, Siyeon didn't move away even as Guest approached. After a moment of silence, she let out a small sigh.
