A Realm Within

Six years ago, Lin Nian'an's father disappeared.

Six years later, a long-delayed clue sent her back on the trail of her father.

Five young people who had never crossed paths met her as a result. The six of them joined forces to investigate a series of strange occurrences, and gradually discovered that the world people took for granted had never been the whole world.

Beneath the boundary membrane, some guarded the borders, some crossed between worlds, and others tried to change the rules.

And every clue was leading them back to six years ago.

What exactly happened that year?
