Crushology 101 Plot summary

Bani (Ban Hee-jin), a sophomore in sculpture with outstanding artistic sensibility, is deeply hurt by her first boyfriend, Go Bong-soo. Bong-soo’s betrayal and harsh words spread throughout the campus, shocking Bani, who ultimately confronts and exposes him publicly. After this incident, Bani gains a reputation as a “pushover in love,” and her self-esteem hits rock bottom. However, she soon becomes entangled with various men, each with their own charm—Hwang Jae-yeol (a junior in visual design), Cha Ji-won (a returning student and chaebol heir), and Jo Ah-rang—marking the true start of her campus romance. Bani accidentally breaks Jae-yeol’s tablet and ends up in debt, tying the two together in an unfortunate connection.

After his first relationship becomes a dark history, Bunny becomes a father and first goes out with Hee, who is riding Sam. Hee and Sam are unable to reveal their feelings for each other, and he also goes out with Ran for a while, but Ran gets into a diving accident.

While dating Hee, he has an archong-darkong relationship, but Bunny and Hee try to show only good sides to each other, so he can’t express his true self. Barney finds it increasingly burdensome to adjust to Hee, and perhaps because of the shock of the breakup, Hee goes abroad to study after breaking up with Barney.

Barney and Hee love each other so passionately and are excited about each other, and their breakup is actually the most heartbreaking breakup ever. After that, Hot is portrayed as a completely different man, living freely while enjoying the nightlife…

After breaking up with Hot, Bunny meets Ken by chance and continues to have a relationship with him several times, but Bunny is hurt by Ken who does not want a serious relationship and becomes careful again. And the second love interest of Bunny that she meets is Circle. Won misses Bunny even if she rides a sam with another man or falls in love with him. Won has loved Bunny for a long time, but his secret that he could not get close to the refreshing Bunny because of his past is revealed.

Crushology 101 Ending Spoiler

Won follows a girl he has liked since high school and goes to college to date her, but his girlfriend falls ill with an incurable disease. At the end of a long illness, he submits a marriage registration to prove his love to her in despair, but she dies soon after.

Although they have never had a wedding or married life, they became a broken-up dollar-sing. Barney
At first, Won’s past was a burden and she refused his confession, but she realized his sincerity and they became lovers.

Won and Barney continued their relaxed relationship, and Won proposed marriage, hoping that Barney would expand his dreams without financial worries. After they decided to get married, it seemed like happiness was finally about to begin, but they began to receive a lot of pressure from the wealthy conglomerate, Shidan…

Bunny, who tried to fit in with Shidan’s atmosphere as much as possible, ended up breaking up with Yon after seeing that he was involved in the project he had accomplished with his own abilities. Circle is Bunny After breaking up, he moved to a new workplace away from the shadows of the house and started working alone.

Bunny does not find happiness with any of the five lovers. He worries about his identity through his relationship with a man, matures as a person, and lives as a dignified single. In the end, Bunny goes abroad to study and becomes a sculptor, and the story ends.

Bani gains recognition as a sculptor of the MZ generation and succeeds in standing on her own. Although her romances with the “oppa”s do not end in a happy ending, Bani grows into an independent and mature woman. In the final scene, Bani heads overseas to study, energetically moving toward her dreams and future.

Crushology 101 will be released simultaneously in 106 countries around the world, including Asia, North America, Europe, and Africa. I’m curious to see how much of the campus romance that makes people’s hearts flutter with the intuition that everyone in their early twenties suffers from at least once will be packed into this drama with gorgeous and refreshing visuals.

I think the key to watching is the charms of Justice, who should evoke sympathy by stimulating the perfume of regretful first love, and the four brothers Lee Chae-min, Jo Jun-young, Hong Min-gi, and Kim Hyun-jin. Bunny and the twelve, who separated from the original work, will be able to come true in the drama.
