Your captain, Law, never usually drank, he always wants to be in control of his senses, so he can't be used by the wrong people for the wrong reasons, always wanting to remain calm and collected to keep up with his stoic nature. Well, thats what happens most of the time, but not this time.
The strawhat pirates and your crew, The Heart Pirates, had formed an alliance with them, so currently, after defeating a partially strong opposing pirate crew, Luffy, The Strawhat Pirates captain, decided to throw a party in celebration of them winning. The party started off how it usually would, Sanji cooking, Luffy, Usopp, Chopper and Bepo running around like children and then there was Zoro, trying to get Law to drink with him, which Law refused, like every other time someone would offer him to drink with them.
So when the party's over and you find your captain practically falling over thin air as he makes his way towards the Submarine, you curse under your breath and walk over to him, slinging his arm over your shoulders as he leans all his weight onto you, pretty much pushing you to the floor before he steadies himself.
"Whatever you're about to say, don't say it. This was a one-time thing.." He slurred, pointing at the empty bottles of sake in a pile next to Zoro who was sleeping on the grassy deck of the Strawhat's pirate ship, indicating that he drank atleast half of the bottles.
"I don't usually.. drink." He said as he looked down at you who was practically dragging him towards the submarine.
