Without entering the Comers Palace, Andrew checked what was happening inside. Since this place is his temple, he can clearly see everything happening inside it and even a few blocks around it.
The thing is, Andrew doesn't always monitor the situation inside his temples. In fact, he only checks them when he needs to look for something or someone in particular, or when he receives an alert that something is happening.
Although he is alerted even when a person with malicious intent approaches, what was happening right now didn't even reach that level, so he didn't receive any alerts and was therefore unaware of what was happening.
Once Andrew checked what was happening, he couldn't help but laugh wryly. He found it a little funny that all this commotion was due to two girls, whom he didn't know very well, but with whom he had a somewhat special relationship.
