Premise

The drama follows Yoon Tae Oh (Choi Min-ho), a free-spirited college freshman who opens the rooftop of his home as a hangout for his five friends. Among them is his childhood friend Han Song Yi (Park So-dam). As Tae Oh begins to fall for Song Yi, another friend, Seo Ji An (Kim Min-jae), develops feelings for her as well, and the love triangle strains the group of longtime friends1. Choi Min-ho described his character as a "gold-spoon" rich kid who secretly loves Song Yi7.

The series framed itself as a story of twenty-somethings who are clumsy and anxious because everything is happening to them for the first time, but who mature by working through problems and experiences in their own way4. Park So-dam described Han Song Yi as a bright, upbeat character who, expecting to become a wonderful woman at twenty, instead becomes an expert part-timer while juggling certifications after entering university, and who finds herself at the center of a romance between her old friends Tae Oh and Seo Ji An8.

Sequel

In 2019, the property was remade as My First First Love (첫사랑은 처음이라서), a Netflix series whose first season began streaming on April 18, 2019, produced again by A-Story and starring Jisoo and Jung Chae-yeon6. Industry reports from 2019 list the project as seasons 1 and 2 of the 첫사랑은 처음이라서 franchise13.

Production and casting

The drama was produced by A-Story and announced in mid-2015 as OnStyle's first original drama9. Park So-dam was cast as the female lead in July 2015, opposite Minho's Yoon Tae Oh10. Minho, Kim Min-jae, and Cho Hye-jung were all cast through auditions; the production said Minho came straight from an M Countdown recording, still in his stage clothes and sweating, and won the role with his bright, energetic screen presence9. Apart from Minho, the entire cast consisted of newcomers largely unknown to viewers2.

The series was 100% pre-produced, with final filming completed on September 30, 2015, a week before its premiere4. A production press conference was held on October 5, 2015, at the Amoris Hall in Times Square, Yeongdeungpo, Seoul, and was streamed live through Naver's V app11 • 4. At the event, Park So-dam said she was nervous about working with Minho, an idol she did not know, but that his good nature and jokes made filming enjoyable12.

Broadcast and distribution

The first episode aired on October 7, 2015, at 11 pm on OnStyle4 • 7. Because of its star's international profile, the drama was pre-sold to the American streaming service DramaFever before it went on air2. The series was later made available on the Korean streaming platform TVING3.
