Aurora lights and wandering hearts

Sheng Shaoyou climbs out of his own wedding through a kitchen window and doesn't look back until a stranger on a train offers him tea, a border officer needs two names on one form, and by noon the next day, he's accidentally married to a man he met twelve hours ago.

Hua Yong has one goal in life: see as many countries as he can, and never let a floor stay under his feet long enough to trust it. Marriage was never part of the plan but neither was the man across from him on that train.

What starts as a two-week detour to undo a paperwork mistake turns into ten days trapped in a snowbound village, one stove, one bed, and a marriage neither of them can quite bring themselves to end. Between fire-building lessons, small domestic wars over socks and itineraries, and an old innkeeper who insists on standing witness to a wedding that was never supposed to be real, two men who have spent their whole lives running one from a cage, one from ever staying long enough to be caged again finally have to sit still long enough to ask what they're actually running from.

Under the aurora, they find out.
