Morlan and Lamina love Nexus as much as they love their biological sons. It was without a doubt that they also prepared Nexus to inherit one of the Harlexis family businesses.
Morlan and Lamina already think of Nexus as their own biological son, and they won't treat Nexus differently from Laxus and Alex.
They are only godparents for Nexus, but it is not any different from biological parents who pampers their children rotten. Anyone who sees how they treat Nexus, maybe they will think Nexus is their own son.
No one can believe if someone tells them that they are only godparents for Nexus because their treatment with Nexus isn't different from Laxus and Alex.
Nexus is one year older than Alex and two years younger than Laxus. Nexus is different from Laxus and Alex since childhood.
Laxus and Alex always put on a serious expression on their face, while Nexus excludes gentle aura and his sweet smile on his face.
