[ It's a good question. For Riou's part, he processes things by finding his private space. He focused on building that space for the last month that Samatoki was gone, but he could've gone to Jyuto any time during that. Instead, he got sick from spending too long in the wilderness, slept with Sasara, and built a table.

Now that he thinks about it, he wonders if he was spiraling in his own way rather than it just being the reason he was upset when Jyuto contacted Solon instead of him directly. He's confused about why he didn't come and share with Jyuto himself, so he answers why he didn't confide in him about being Solon instead. ]

I thought if I revealed myself, you would stop coming to both me and Solon. I want to be there for you, even if I had to lie to that end.
