Eunbi thinks the world is ugly. For Sojung, the world is beautiful. Eunbi wants to forget. Sowon needs to remember. Eunbi keeps on appearing, she doesn’t want to. Sojung bounds to disappear, she wants to stay. Eunbi is keen on running away. Sojung has a bucket list she wanted to fulfill. The time their worlds collide into each other, it's the time where yesterday meet today.
