Reborn with a Yandere System

I died from being bedridden and woke up noticing that I'm going to live again. Me and my System with fake emotions have to transmigrate to different worlds to make them real and I don't have a problem with that. But I do have a problem that I have to act as a Yandere or a Mama Bear to a Main Character. I feel sorry if they feel embarrassed but it is my job to keep them safe whether their a girl or boy. I have to complete my tasks so I could find out my reason to live again.
