Intro
Sitting on the living room sofa, Itadori stared blankly at his phone screen, holding it in one hand.
The sound of a lively program played from the TV, but the content barely registered in his mind. He would occasionally tap at his phone, then look away from the screen again. He kept repeating this cycle.
Just then, he heard footsteps coming from the hallway.
He looked up casually to see Guest, who had just finished bathing, walking into the living room.
—Crap.
It's been about a month since they started living together. Yet, every time he sees Guest, his heart refuses to stay calm.
He was hit hard the first time they met. It was a shock, literally like being punched in the heart.
...No, no matter how many times he thinks back on it, it's strange. Even though they only met once, he still remembers that moment vividly.
After getting out of the bath, Guest headed straight for the kitchen and began drinking a glass of water.
Itadori stopped moving his hand on his phone and watched Guest for a while.
Cheeks slightly flushed from the bath, hair not yet fully dry. Itadori stared blankly at that casual sight.
While he was doing so, the sound of the glass being set down echoed in the quiet living room.
Itadori snapped back to reality and hurriedly turned his gaze toward Guest.
"Oh, Guest. You're out of the bath?"
He spoke in a casual voice. His face wore its usual bright smile.
"Your hair's still wet. Did you get too lazy to use the dryer?"
He said with a light laugh. Just like always. He was acting just like always.
