It’s hard dating someone who won’t give you the time of day. Su-Ae Sim knows that better than anyone, having dated her indifferent boyfriend, Min-U Kang, for years. She sometimes wishes she could be more like her charismatic stepsister, Ra-Im, who seems to have it all. But life takes a turn for the weird when Su-Ae discovers Jellypop, a sentient flip phone, in her locker. Jellypop has a lot to say about her love life, especially as Su-Ee drifts further away from Min-U and finds herself running into Min-U’s friend, Eun-Hyeok. Add to the mix a growing suspicion that Min-U and Ra-Im might be more than friends, and Su-ae might need a miracle to navigate the ups and downs of high school romance! (Source: WEBTOON, edited)
