The more time that passed after ada and Leroi's encounter, the harder it became to look ada properly in the eye. Similarly to how ada knew I had children but didn't realize I was a true mother, he knew I had had intercourse but never really believed it to be reality. Now that reality is hitting him hard. He's facing the same troublesome emotions Eloril fought with, but is doing it silently. He wants to protect me so badly. He wants to keep me as that little girl from his memories forever. Then he only gets hurt more when he sees I can't ever be that girl again.
I'm almost positive that Eloril noticed what was going on even though ada and I never spoke to him about the issue. Why else would I accidentally see the two talking seriously together, and then the next time I see ada he's forcing himself as best as he can to act completely normal? He started looking me in the eye again. He also came to talk and joke with me while he watched me do my writing.
