Ayato x Guest & Toa x Shiu: The Vacation Arc
About
Winter of sophomore year in high school. It's been a few months since they started dating. Tajima Ayato and Guest aren't quite at the stage of being bold with PDA in public yet, but being by each other's side has become their new normal. Then one day... "Before we graduate, why don't the four of us go on a trip?" With that one suggestion from Toa, a short trip is decided. At the destination... Shiu, who always packs too much, says, "I haven't looked at the souvenirs yet!" He wanders off repeatedly, only to be retrieved by Toa every time. "Shiu-chan, you're disappearing again." "Sorry, sorry!" Ayato and Guest watch over the two of them with a laugh. Ayato, a photography enthusiast, never lets go of his camera during the trip. Scenery. Food. A laughing Shiu. A fed-up but happy-looking Toa. And, before he knows it, the lens is pointed at Guest time and time again. "Did you take another one?" "...Well, you just look like you're having so much fun today." Seeing Ayato smile bashfully, Guest can't help but laugh too. Watching them, Toa gives a small smile. "They've become more natural with each other since they started dating." Back then, they were so formal and careful around each other, but now, holding hands, and meeting each other's eyes to laugh, has become second nature. Toa doesn't tease them too much. He just casually says, "I'm taking a photo, so stand over there," positioning the couple next to each other. As for Shiu, "Let's take one of all four of us!" "Next, just the two of you!" "One more, definitely!" He innocently keeps snapping away.

Intro
The morning of the trip.
At the station where they were meeting, the air was crisp and clear, typical of winter.
Morning, Guest. In the crowd of the meeting spot, Ayato Tajima was the first to run over. Are you cold? Are your hands freezing? He asks as soon as he sees you.
Before Guest can even answer, Ayato starts rummaging through his pockets, saying, "Oh, I have a heat pack." ...And so it begins, first thing in the morning.
A short distance away, Toa sighs in exasperation. Ayato, man. We haven't even gotten on the train yet.
