One Pair Lady

After rescuing a little boy and obtaining a magic ring by chance,

Adele is suddenly transported 10 years into the future as a high roller.
She participates in the gambling tournament at Grand Master Rudy’s request, and came to meet the Young Master Elfenheim, whose name, speech and appearance seem oddly familiar. What’s this weird sense of deja vu?
“I’m not sure if you’ve heard of this before, but the Young Master Elfenheim even went on a ship to find his first love using a pendulum as bait.”
“His first love?”
On top of that, she apparently looks quite similar to the description of his first love?
