The rising heartthrob has been steadily gaining fans ever since 'A Gentleman's Dignity' and 'To the Beautiful You', but these new photos, posted under the title, "'The Heirs' Kim Woo Bin, high school graduation photo", show a more studious side to him. However much or little he's changed from then to now, it's clear that he never lost his charisma.

Netizens responded, "Something's lacking," "He still looks the same," "He has charisma," and more.
