After impulsively helping him, he proposes marriage, claiming it would be his family's requirement after their first kiss.

He never expected this hidden truth to resurface until the moment he reveals his true self to her. As their marriage progresses, Owen fiercely defends Stella against those who criticize her unconventional behavior, insisting she is well-behaved and innocent. Stella, meanwhile, grapples with her past and gradually discovers Owen's carefully guarded history. What began as a flash marriage becomes a journey of mutual redemption, where both find healing through their unexpected bond and emerging love.
