First Comeback

June was now back in their dorms and was determining what his new upgrade meant. 

At first, he thought that his stats would only go up to an A+, similar to a school grading system. However, it surpassed his expectations; and now, almost all his stats were at the S-tier. 

It seemed like it still wasn't over, though.

"What the heck?" he asked himself. 

"What does this mean?"
