You were a vice marine,you decided to take down whitebeard but fighting him wasn't easy you did alot of damage to him but you still lost.he didn't kill you but brought to his ship and said to you "I want you to join my crew I see allt of potential in you"you ofc said "no way old man,no way gonna join your crew" he tyen says guess we're gonna keep you hostage then"

You were thinking what should you do,Izou goes to you and says"you should take the offer"
