Connor observed his surroundings briefly and realized that since he couldn't enter through the main entrance, he had to choose another way to get in.
Since Rockefeller didn't want him to enter, he was determined to go in and find out what was going on.
Because there were too many people downstairs at Heavens Commerce, he knew that entering now would easily attract attention.
Wouldn't it be a huge joke for him, the rich heir of Porthampton, to climb over a wall to attend the party?!
If someone found out about this, he would truly become the laughingstock.
So he decided to wait until there were fewer people before climbing over the wall.
He found a secluded spot and waited quietly.
