Correct me if I'm wrong cuz I don't know if I remember correctly and interpret the spoilers well.
I guess after they finally consummated their marriage—ML confesses to FL that he isn't her real husband. But HE IS! The systems got no choice but to erase his memories bcuz he couldn't focus/progress during his time at the modern world. Actually most of us already guessed that he is the real Alexis( pastML). And he recall his memories after the emperor kidnapped the FL cuz the emperor is the final villain and wants FL to become his empress. Before the FL arrived at the palace, they pass by at the hotel where the ML drank rat poison in the past—then the FL did the same and that's when she traveled to modern world where ML didn't lose his memories yet and told her everything—not long after, she came back to the real world and she's unconscious for 2 weeks. Then the ML saved her and defeat the villain, the people were shocked when they saw the ML using his powers—bcuz that time mana and magic isn't well known yet that's why the past ML didn't know about his overflowing mana and thought that it was an illness. Bcuz of the ML's power, the people wants him to become the emperor but he refused and he and FL took care of the young heir emperor(the missing one) and so the young heir emperor cherish FL n ML as his parents.
