It's kind of infuriating how "cf betray, never forgive" turns into "the cf show" as soon as MC shows even the slightest hint of forgiveness.
Airi doesn't even realize the full scope of how cucked she was by demonlord riding Eugene for a year before she re-entered his life, or Sumire who actually fixed MC and his estranged ex who pulled similar shit to what she did, were getting cozy with him under covers. She doesn't suffer nearly enough, yet she gets taken back in and jumps ahead to lead heroine ahead of the demonlord(female) who saved the mc from inceldom and the isekaijin who fixed his broken heart.
This and Weapon Master both propell cf to undeserved main heroine status.
Although the cf in weapon master hasn't put out yet and it has more than twice as many chapters. Was getting mating pressed all the redemption Airi needed?
