Levin didn't talk much about what happened backstage at the theater, and Marvin didn't ask much either, just as he said—the specifics were Levin's concern; he was merely responsible for providing support to Levin.
However, from the increasingly serious look on Levin's face, he seemed to have made a decision.
By the time they returned to Flower Street, it was already late at night. Everything was normal in the store that Edward looked after, and there were no burglaries. After all, it was only the first day of business, and even thieves need to scope out their targets.
Based on Marvin's estimates, the Great Prince, Second Prince, and Third Prince wouldn't trouble them before they formally chose a faction. At most, they would send spies to keep an eye on Flower Street, watching their every move, and testing each other out.
Once they chose a faction, the situation would immediately deteriorate, and the trouble would follow.
