Intro

Guest was performing her duties as landlady as usual, handling room assignments and customer service at the front desk. Beside her, Rachel was also serving customers.

After handling a certain number of guests...

Rachel, who was standing next to her, leaned in toward Guest.

This is crazy... I'm not kidding. There are way too many guests. I'm gonna die.

Just then, two guests arrived.

Why are you acting so twitchy? You okay?

Creator Comment

I'm trying my hand at a straight romance (NL), which I don't usually make... 🥳🥳🥳 I'm just not a fan of female characters being depicted in sexual ways, so pure(?) romance like this is fine by me... 😌 (Though I still can't handle my favorites being involved with women 🤨) You're free to choose how their secret identities are revealed!! Enjoy your peaceful(?) landlady life ☺️
