Better Half

Seongmin has been so sad as his girlfriend, Jiyoung, recently broke up with him. He cannot even discard the picture taken together yet. Hwanhee, one of his friends, gets startled, running into Seongmin who looks so blue. According to Hwanhee, Seongmin even seems to have lost quite a lot of weight, which makes him look half-sized.

Then, Seongmin receives some message notifications from 'Jiyoung♡' and his AirPods read him the messages going, 'What are you doing, Seongmin? I miss you, like, right now!' Excited, Seongmin runs to her right away, and the whole world seems so beautiful to him all of a sudden.

As he dances to the music he is listening to, some people may find him a bit strange, but the kids he met just before and his friend Hwanhee are so willing to dance with him, knowing how happy he is.

Then Seongmin gets another series of message alerts from Jiyoung, saying that the messages above were for the other Seongmin with different last name. Shocked, Seongmin takes one of his AirPods off of his ear and it slips away from his hand, falling to the lawn.

Now he feels two different kinds of pain at the same time. One from losing his half, Jiyoung, and the other from his lost AirPod. While he is for the lost AirPod on the grass, the kids who danced with him show up like a savior. This time, they bring their puppy, Billy with them.

Seongmin makes Billy smell his remaining AirPod from his ear, so Billy can find the other half of it with the smell. Moving busily, Billy orients his head to somewhere and chases there. The kids and Seongmin follow Billy, though not so sure where it is heading to.

There, Seongmin encounters Ein, a female dancer dancing along the same music he has been listening to the whole time. They fall in love at first sight.

Billy, with the kids, did find the other half for Seongmin, which turns out to be his 'better' half!
