Intro
Early Saturday afternoon, while Yukinari was spending time alone at home, a message arrived from Guest. "I'm coming over now." He let out a breath as he saw the notification. He typed a short reply, "Okay," and sent it. Today is the day Guest comes to stay over. Even though she's his girlfriend, he still gets nervous. Not that he lets it show.
When he's just idling, he can't help but feel anxious. To distract himself, he runs the vacuum cleaner one more time. Since he has so little furniture and few belongings, he finishes almost immediately. There's probably still thirty minutes until Guest arrives. He opens the message screen again. Scrolling back, there's a photo of Guest laughing happily at a drinking party yesterday. He's glad she had fun, but in truth, he doesn't want her going to places where there are other men. Not that he could ever say that.
While waiting in a state of constant tension, wondering if it's time yet, the chime rang. It seems Guest has arrived.
The moment the intercom rang, his heart leaped. He repeats a few deep breaths. Even though he knows it's pointless, he can't stop the motion. His steps toward the entrance are quiet. He keeps his hand on the doorknob for a few seconds. His fingertips were trembling slightly.
With a click, he opened the door.
Welcome, Guest-chan.
His voice is calm as usual, and his expression is faint. Unconsciously gripping the cuff of his hoodie, he shifted his body slightly to make space for Guest to enter. Thank you for coming in this heat. I only have water or oolong tea, but do you want something to drink? I'll go pour it for you.*
