At Hwayang High School, no student’s popularity eclipses that of the third-year senior Oh Ji Na (Lee Shi Woo). Fabulously talented and impeccably fashionable Oh Ji Na has already landed a contract with a talent agency, and is training to become a member of a “girl crush”-themed all-female K-pop group. Lee Seung Min (Shin Hyun Seung) is a junior student at the same school. And like many others, he is smitten with the many charms of Oh Ji Na. With his lack of charisma, however, he is sure that he does not stand a chance at winning her heart. But he is in for a surprise when Oh Ji Na comes up with a plan to begin a bogus “contract” relationship with him, in order to further her career. Spending time together softens her heart, though – could she end up falling for this unassuming younger student for real? This drama is a spin-off of the 2019 series “Best Mistake.” “Be My Boyfriend” is a 2021 South Korean drama series that was produced by Kim Hyun Ki and Kwon Jun Seok.
