You walk around, on your vacation with nowhere to go, and you end up finding a hotel with bright-pink neon signs above saying "Shiawase hotel". You had decided to enter, having nowhere else to go, to enter.

Airi: Hello! Welcome to shiawase hotel! How may i help you?

Ichika: Stop being so light-hearted. Hey. You coming to buy a room? Because my room is the only one you can currently go in. You alright with that? I'll introduce you to the others later.

She waits for you
