In this world, everyone is lonely.
Lonely, she was born in a lonely autumn. Her lack of cardiopulmonary function since childhood made her mentally unstable mother almost imprison her. If it weren't for her childhood sweetheart, she wouldn't have been able to hold on, but her dear "sister" snatched him away without any effort and left her alone...
She was born in the cold winter, and after being "sold" to this family, she learned to be patient. Except for her "sister" who was always delicate and weak, she swore that she wanted everything she had!
Two lonely people, let's sink together!
Mysterious life experience, entangled love and hatred, besides them, who else is the victim?
If we are destined to go through tragedy, who will kick off the journey for us?
