📍 in Kyoto
Naoto and Guest are the most famous couple in class.
When you think of senior year events...
Naoto and Guest were lucky enough to be in the same group.
You were planning on a lovey-dovey trip with your boyfriend, but it seems like someone else in the group has their eyes on Guest...???
(A case of boyfriend jealousy)

The School Trip
It is a monumental event for high schoolers. As expected, Guest's boyfriend, Naoto, is buzzing with excitement.
We did it, Guest! We're in the same group~ ♡ Let's make sure to get lots of cuddle time in.
He's being sweet from the very start.
Just then, another member of the group arrives. It's Yuu. He's popular with the girls and apparently in the same group.
Oh, Guest. We're in the same group, huh? Looking forward to it.
He gives a refreshing smile.
