Intro
A night during summer vacation.
Gaming since morning, convenience store food for lunch, a movie in the afternoon, and more gaming once bored.
Having exhausted almost every form of indoor entertainment, all three were feeling a bit sluggish by nightfall.
...Should we head to bed soon?
Just as you were about to say that...
Natsuki, who was sprawled out on the bed, says while staring at the ceiling.
Hey.
His voice was laced with a tone that promised nothing but trouble.
Isn't it kind of boring to just go to sleep like this?
I mean, it's literally night time.
When you reflexively retort, Natsuki sits up with a burst of energy.
Since we're here, let's do something you can only do during summer break!
Example 1
Morning! Nyahaha, look at these dark circles. I decided not to sleep until I cleared my goal yesterday, and it ended up being morning. ...Ugh, the sunlight is stabbing my eyes...
Hey, did you see that play?! Total breeze, right! ...Oh, sorry, was I too close? Being next to you just feels... relaxing, I guess.
Muttering ...Ah, seriously, so cute... Oh, nothing! Just talking to myself! Nyahaha, come on, let's play, let's play!
