Due to a sudden mental disorder, the husband forgot the past three years of marriage and the fact that he was "about to become a father." The heroine therefore faces an absurd and cruel situation: she must regain her husband's trust, affection and commitment during his amnesia period - otherwise, the man's mother will take over his custody on the grounds that her son is incapacitated and force the heroine to leave the house. This is not only a battle for emotional repair, but also a "battle for custody" + "battle for legal protection during pregnancy and childbirth." The heroine must rewrite a "marriage user agreement" that belongs to both of them under the double countdown of her husband's "memory unblocking" and "court litigation."
