Fatal Trouble

It's hard dating someone who wont give you the time of the day. Moon Eunbyeol knows that more than anyone, having dated her indifferent boyfriend, Cha Euntae for years. She sometimes wishes she could be more like her charismatic stepsister, haneul, who seems to have it all. But life takes a turn for the weird when Eunbyeol discovers jellypop, a sentient flip phone, in her locker. Jellypop has a lot to say about her love life, especially as Eunbyeol drifts away from Euntae and finds herself running to his friend, Sunghoon. Add to a mix of a growing suspicion that Euntae and haneul might be more than friends, and Eunbyeol might need a miracle to navigate the ups and downs of highschool romance!
