Bubble de House de Marumarumaru The Animation Episode 1

Four months ago, I tried to move into a student share house that a certain famous bath manufacturer was offering at a low price on the condition that I test their products, hoping to get cheap rent... I thought I had completely missed out, but then I came in second and was accepted!!! I was overjoyed and moved in, but...I realized that all the residents in the share house were girls except for me!!! What's more, they were students in the same year above me who attended the same university!!! It was tricky to only know each other one-sidedly... It seems like there's a lot of excitement in this... An exciting student communal life began in this "bathroom space".
