I've read the scenario of maid bullying their mistreated master quite a lot these days and most of them have inferiority complex about themself and see their master as the perfect target to take out their frustration,,, i guess it's almost the same with what happened in real life and seeing the bullying rate in S. Korea, i do hope that the people who read these manhwa realized that as long as they show how they can have the strength to stand up without relaying to no one will be the most effective method to stop the ill treatment. And just find that inner strength within ourselves, even if we didn't go back from the future or reincarnate, but if you already overcome bullying even without standing up for yourself i think it's okay too because you show your strength by staying alive and strong until the present.
Errr, thank you for translating this series!
