I had to really search for this show and finally found it on Tubi TV under the title "My First Time." It's a short series, only 8 episodes, that was later remade as "My First First Love" in 2019.

I wanted to see this show because it stars a couple of young actors who have subsequently become famous since this series played in 2015: Choi Min-ho (whom I loved in Hwarang), Park So-dam (Parasite, Record of Youth, Cinderella & Four Knights), Kim Min-jae (Guardian, Hit the Top, Dr, Romantic series), and Im Yoon-ah.

I loved how the backstory of each character was told throughout the series. The great question was "which guy will the female lead choose?" I won't give away the answer but I admired her for sticking with the guy she initially liked and did not waver.

The story, soundtrack, and acting were great!
