Mar 13, 2025

MBC’s upcoming drama “Crushology 101” has unveiled an adorable new teaser!

Based on a webtoon, “Crushology 101” is set in a university and follows the growth story of Ban Hee Jin (Roh Jeong Eui). After experiencing heartbreak from her disastrous first love, she finds herself entangled with handsome men.

The newly released teaser offers a closer look at Ban Hee Jin’s unpredictable campus life. It opens with her voice-over: “As a child, I chose fairy tale books based on whether there was a handsome man on the cover.” A classic storybook prince then appears on-screen, perfectly encapsulating her approach to romance. However, her dreamy moment is abruptly shattered when a voice jolts her back to reality: “You are under arrest for delusions of grandeur!”—infusing humor into her idealistic fantasies.

Ban Hee Jin’s life quickly spirals into a whirlwind of chaotic entanglements. First, she’s caught in an exasperating game of cat and mouse with Hwang Jae Yeol (Lee Chae Min), sighing in frustration, “What is wrong with that guy?” as her picture-perfect romance crumbles before her eyes. Meanwhile, Cha Ji Won (Jo Joon Young) remains by her side, his warm and considerate nature drawing her in. As they work together, an undeniable spark flickers between them, hinting at a budding romance.

Adding to the mix, Jo Ah Rang (Kim Hyun Jin) effortlessly steals the spotlight with his subtle but swoon-worthy gestures—kneeling to tie Ban Hee Jin’s undone shoelaces and stepping in to protect her at crucial moments. Meanwhile, Jin Hyun Oh (Hong Min Ki) gently ruffles her hair with a soft smile, sending hearts fluttering with his quiet yet captivating presence.

As the four strikingly different “oppa” figures each showcase their unique charms, the dynamics between them and Ban Hee Jin grow increasingly tangled. A hint of jealousy emerges when Hwang Jae Yeol grumbles, “Why is he ‘oppa,’ but I’m ‘sunbae‘ (senior in Korean)?”—suggesting a subtle shift in his emotions. Meanwhile, the tension reaches a boiling point when Cha Ji Won, who has clashed with Hwang Jae Yeol before, confronts him with a sharp remark: “Is making fools out of the people you trust really what you wanted?”—raising curiosity about their complicated relationship.

As Ban Hee Jin becomes overwhelmed by the relentless flurry of flirtation, she blurts out, “Does he like me?”—but who exactly is she talking about? And more importantly, where will her heart ultimately lead?
