When Itsuki entered his room, he too came to realize that it had been a while since he last saw Histoire. He immediately assumed that she had left his room earlier and returned and stayed in there with his sister. So he did not think too much of it and closed the door to feel some tension lingering in the air.
"What's going on? Why are you two so quiet?" He asked and sat down next to Tsuki on the bed. Histoire was still seated on the chair with a pensive look about her. Tsuki sat up in the bed.
"I'm trying to make her see that Deus likes her," she said and Itsuki spared a glance at Histoire. It was fairly obvious that Deus thought of her as something more than a friend, unlike Histoire who treated him as though he were an old friend. But that was not something that had bothered her before.
