Help finding this manga

I believe it was ecchi? Anyways, MC (f) lives in a sex hotel, which is a castle, with her single mom. MC tries to hide the fact that she lives there since she is a student president in her school. She has a when it comes to dealing with their hotels male guests where she sweats profusely if they touch her (the first time it was shown it looked like she peed herself). The problem comes when a playboy cmate finds out her secret, since he was with a diff woman inside the hotel for some snu² and happen to catch the MC serving them their food. As usual, playboy tries to blackmail her with that information (f'cked up, I know) and that's all I could remember
