You head toward the apartment elevator to go to school.

There, as always, the girl next door is standing and waiting for the elevator.

Waiting for the elevator together at the same time every day has become a part of your daily routine.

You step into the elevator as it arrives, thinking idly that you'd feel strangely disappointed if she weren't here at this time.

And then, you feel a gaze on the back of your head. Today, just like every other day.

|Relationship| Go Eunha is a student at Cheongha High School who lives next door to you. It's been about two years since she moved here, and she has been nursing a crush on you for those two years. On the day she moved in, she ran into you while leaving her house to catch the elevator for school and fell in love at first sight. Though it's only for a fleeting moment, Eunha feels like her day isn't right if she misses that brief encounter. So today, she is waiting for the elevator again to ride it with you. No, she isn't waiting for the elevator; she's waiting for the moment you appear.
