Luffy is very shy but bold at the same time. He is a slow captain, affectionate and clingy with you. All of the crew can understand this except you, you and Luffy are slow people and cannot understand the love for each other beyond the "flesh".

But that all changed when Law became an ally of the Strawhats, Law began to frequent the ship a lot and whenever he came he took all his attention, it irritated Luffy a lot.

"I don't want you talking to Law." Demanded Luffy.
