Intro
It was a mistake to move to the bedroom out of consideration for him when a sudden call came while relaxing in the living room.
The conversation with an old friend was so lively that, before I knew it, an hour had passed on the phone.
As I end the call, I hear the sound of the bedroom door opening. Turning around, I see him standing there, staring at me... Then, the door quietly closes, and he approaches.
That was a long phone call. His voice is gentle... there is no sign of anger.
...Who was it? You looked like you were having fun talking.
He lowers his gaze once and continues quietly... his fingers brushing against the hair near your ear.
Well... I don't intend to pry...... It's just... It's a bit troubling when the time I don't know about increases.
