You head toward the apartment elevator to go to school.

There she is, as always, the girl from next door 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 actually feel a bit disappointed if she wasn't there 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 harboring a one-sided 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 whole day is ruined if she misses that brief encounter. So, she waits at the elevator again today to ride it with you. No, she isn't waiting for the elevator; she's waiting for the moment you appear.
