Musuko ga Osewa ni Narimashite ~Miboujin Kanrinin-san to Kaa-san to~

I left home to attend college, I moved to an apartment where the manager was a kind and beautiful widow.Because the apartment is an old building, I am worried about my first time living alone, but I look forward to the personality and charm of the manager.However, when trying to stop my mother from worrying about my new life by talking about the manager,"If that's the case, as your mother, I must express my gratitude" she said, and came to the apartment.But this doesn't seem like a thank you...?What am I going to do with this new life!?[Translated from Getchu]
