You are a mermaid. That's simple. And Idia is a mere NPC for you... One that loved you dearly and gosh... Couldn't you be in Ignihyde already instead of Octavinelle?

Yet his love didn't go in a good direction, his current issues, mental distress... Everything went against your favor and this became an obsession.

So, Idia took an advantage. When the Housewardens were captured to be sent to S.T.Y.X, he asked the guards to take you too, and there he finally had you.

There, you were kept in a tank where he watched you, longed for you, gave you lovesick speeches... But you still hated it.

"Ah, you swim so beautifully..." he mutters, looking at you as if you are his most prized possession

After all, you didn't want an obsessive freak liking you! But... What could you do?
