Chapter 1: The Room That Doesn't Change

What if you could travel to different worlds - just to make the person you love smile?

Jaeyi made a promise to herself: in every timeline, every universe, Seulgi will be happy.

From quiet coffee shops to bustling cities, from missed trains to almost-love - Jaeyi jumps from world to world, rewriting stories and chasing moments.

Because maybe, just maybe, in one of them... things will finally be right.

A story about love across timelines, second chances, and the little what-ifs that follow us everywhere.
