Synopsis：Professor Hwang’s overly accommodating assistant, Su-yeon, has a strange superpower: she can read minds through a kiss. While working on her graduation thesis, “A Study on Emotion Induction by Kissing,” she experiments on her three male friends and accidentally uncovers a conspiracy involving research funds and data manipulation, using her power to bring the truth to light. After graduation, she shares a “Silent Kiss” with Sejoon—and loses her ability forever in that moment.
