Phones are perfect for sending messages, snapping photos, and most importantly, talking to your friends. One thing Su-ae didn’t account for, however, was that her phone would be able to talk back.

Su-ae discovers that Jellypop, a flip phone stored in her locker, is sentient—and Jellypop has a lot to say about Su-ae’s love life. High school romances are never easy, and Su-ae’s relationship with her nonchalant boyfriend seems to be going nowhere. 

Despite their long history, Su-Ae musters up the courage to break up with Minu after his kiss with Ra-Im. But after hearing rumors of Ra-Im and Do-Hwa’s budding relationship, Su-Ae wonders where her heart truly lies. Not to mention, the handsome Eun-Hyuk also seems to be interested in Ra-Im…

After a collision in the rain, Su-Ae invites Eun-Hyuk over for a change of clothes. However, things take an awkward turn once Sue-Ae’s father gets home.

As Eun-Hyuk learns more about Su-Ae, his interest in her grows. The pair spend more time with each other, which doesn’t go missed by their gossiping classmates. Su-Ae tries to quell the rumours, but Eun-Hyuk seems to have other ideas.
