I really don't ship it at all. Even with the reincarnation, the age difference is creepy. Lucas was a full grown man when they first met when she was a little girl. He only looks like a child but isn't he hundreds of years older than her? Besides, he's been gone for nearly 40 chapters. It's not a good pairing.
So what happens if they both suck? Until the prince finds out she's Morina, he has to at least act like he's picking one or the other.
