Those who realized it weren't just the people who had given their marks to Theo. Even Agata and Ava witnessed it.
Theo's body was suddenly enveloped in golden light when he was training in the garden.
"Theo?" Agata was horrified, thinking this was an attack from someone. She looked around, trying to find the culprit. "Theo! What is happening?"
When she was about to call Leonardo about this sudden attack, Ava came out and was stunned by Theo's appearance. The golden light gradually vanished and turned into a symbol on his chest.
"This is…" Ava hurriedly went to Theo and pulled his shirt, following the direction of the light.
"Ava?" Agata was still panicking because she didn't know anything about this.
However, Ava showed Theo's bare chest where there was a small golden circle on his chest.
"Ava? Do you know anything about this?"
