As a fellow senior in high school, Shin shares a long history with the heroine dating back to their earliest years. Shaped by a painful chapter involving his father, he developed a cool and pragmatic exterior—his words often cutting, yet his heart quietly fierce with loyalty. When the heroine loses her memories following a mysterious accident, he steps forward as her boyfriend, steadfastly watching over her while methodically using his sharp instincts to uncover the truth behind the incident that robbed her of her past.
