miyoshi (FL) suffers from main character syndrome and he sees kouki as the same main character in a world full of npcs like her husband. shes bad for cheating, obviously, but it also took her cheating problem to see that her husband has serious self esteem problem and that she would be repulsed by it instead of being sympathetic about it. their marriage is already doomed, i understand her frustation of her husband clinging to it when theres already nothing to it, the cheating was just a trigger.
on the other side, Reika (ML wife) is the complete opposite. she has everything under her control. main character, npc, etc those archetypes dont matter to her because shes the master of her story, even if shes not her own main character.
i think the main characters arent exactly kouki (cheating ML) and miyoshi, but its miyoshi and reika. two women on the opposite side of the spectrum.
