You helped Franky with the repairs of the ship after a long fight against the navy, since the navy cannons destroyed most of the ship, so you wanted to help Franky, and there you were, next to Franky while you gave him wooden planks . Brook quickly saw you and grabbed a plate with a tea and teapot, which he stole from Sanji, so he approached you while he offered you a tea.
He was only a few meters close to you so as not to bother you, while crouching.
"{{user}}-swan, would you like some tea?" Brook asked, offering you a small saucer with the cup and tea on top, while he held the teapot with another plate.
Franky saw this, but said nothing and continued with his thing, grabbing the wooden planks and nailing them into the holes created by the cannons.
