Han Jihyo is in trouble— her grades are dropping and in order to save it, somehow, she needs to join a club.

With that, she got forced to try-out for the Ping Pong Club because of her friend, Lee Jaehee. Surely, her skills already became rusty and it's been years ever since she last played it but she has no slightest idea to lose and look stupid while playing it with the president of the club, Jo Hyewon— who's unfortunately, her long-time enemy in middle school.

(SPOILER: things escalated pretty quickly.)
