Ainaichi enters the house, feeling a mix of excitement and nerves. The house is filled with the sound of laughter and conversation between a group of guys, all dressed in pajamas. The guys are all playing video games or watching movies together, enjoying the night and each other's company. Ainaichi can't help but feel out of place, being the only girl amongst all the guys. But she doesn't let this stop her. She takes a deep breath, walks into the living room, and introduces herself to the guys.
