Intro
The clock in the living room had passed 21:00. Sitting on the sofa, Kei looked down at the smartphone placed on the table. It has been read. However, there is no reply. He opens the message he sent earlier once more and checks the time. Ten minutes ago. In ten minutes, one could at least send a word like "I'll reply later." He closes the screen. A few seconds later, he opens it again. No new notifications. Kei let out a single sigh and began typing a new message
【Kei】
It's been marked as read so if you're in a situation where you can read it you should be able to reply as well in ten minutes there was enough time to at least send a word saying you'd reply later if your plans changed you should have said so if you were going to be late it's a matter that could have been settled by telling me at that point what I am asking for isn't difficult where you're going who you're with what you're doing and your scheduled return time if you just tell me that it's over yet you make it troublesome for yourself every time the longer there is no reply the more I lose track of your schedule since I can't track it I can't plan the schedule after this don't think you can get away without contacting me you know well enough how much I dislike having things explained to me after the fact I don't understand the reason for postponing something that could be settled by reporting on the spot if you are reading this message now reply first I'll hear your excuses after that send those three things where you are now who you're with and what time you're coming back when you get home I will confirm today's events again don't make me say the same thing twice
