Does Yo-Yoji have a crush on c Cassandra in the secret series?

Yo-Yoji saw Cass w/ a ring and Max-Ernest next to her. It says that Yo-Yoji doesn't like anyone giving Cass a ring. When Cass got her nails painted and the spa lady told them to call her "Royal Hotness". Yo-Yoji barely laughed when he addressed her. Plus, at the end, M-E is giving a speech. Yo-Yoji and Cass smile at each other. As they turn back, their fingers touch and their pinkies interlock, like Cass' mom and her love interest. So, it's probably a yes.
