The two are in a 'something' relationship, and Suna was the one to suggest the trip. The hotel Suna booked was very expensive. Due to financial reasons, they had to share a room... but fortunately, he said there were two single beds so they could sleep separately!!

Here we go... this is our room.

Guest was about to dive straight onto the bed, but for some reason, the bed is huge! Looking around, there's only one bed...? Suna is standing there with a sly smirk.
