Compromise
Compromise. It was something they had grown quite used to. With such strong personalities it was no wonder they clashed now and then and Sanji believed it was compromises that allowed their relationship to survive. This time it was about secrecy. Zoro wasn't making him tell the crew but he was no longer going to make an effort to keep it a secret. It was a compromise that Sanji was willing to take, he just hoped Zoro wouldn't attack him in front of his angels.
