Purely sorrowful and heartbreaking, but there are no tragic scenes in the whole story.
The pacing is a little slow at first (please bear with me; the exciting parts come later) (meekly).
The world is like a finely crafted clock, made up of countless gears that interlock and depend on one another, all driven by the clock's core. Everyone can only go along with this force and cannot break free. When a gear tries to escape its pull, it either fails for lack of strength or, if it has enough strength, breaks because it cannot withstand the strain. There are many such gears, but the clock does not stop when they break, because new gears will always take their place. Now Wang Chen's arrival will change the world's rhythm, like a single gear altering the pace of the clock.
