Misconception

Eric gave it up for Mark and their mother. 

Although he didn't know the reason his mother would become that suspicious because a random model was for the photoshoot, it wasn't enough reason for her thoughts to go that deep.

Also, for Mark, he had no idea how he would use his girlfriend for a photo shoot and people wouldn't suspect anything about their relationship. 

Did he think he was the only smart person on earth? Or did he think people were dumb these days?

"Big brother, please, be more careful next time if you don't want to leave traces," Eric pleaded. 

Instantly, Mark's brows constricted into a frown as the corners of his lips turned downwards. "What are you talking about?" he asked. "Do I look like I'm bothered about Mother's suspicion?"
