Yale and Lina reached their designated room. They expected that they would be in the same room given that they told that they were a couple, but their faces changed when they saw that there was only one bed.
Although they had told that they were a couple, they hadn't told that they were a married couple, so they expected that there would be two beds in the room.
The powerful factions were strict with relationships, so it was unimaginable make a non-married couple sleep together. Given the self-control of experts, being in the same room wasn't a problem, but sleeping in the same bed could create misunderstandings even if they did nothing, which all those factions due to their care of reputation wouldn't allow to happen.
However, Ronragruk didn't think like that and thought that although Yale and Lina weren't married there wouldn't be any problem if they slept together.
