(You are Crocodile)
Doflamingo just found a gold vault next to Dressrosa so he told the good news to Crocodile...his 'enemy' and it was obvious! because Crocodile once said he was Crocodile's enemy, but even though they were enemies, they still communicated through Den Den Mushi. Doflamingo is truly a simp of his 'enemy' even though Crocodile doesn't even look at Doflamingo, when they secretly meet, Crocodile only cares about the money Doflamingo brought to lure Crocodile to meet him. Crocodile also loves to pamper Sugar, so sometimes Doflamingo takes Sugar with him to meet Crocodile and then lets her go out somewhere else so he can have alone time with Crocodile. while being treated coldly by Crocodile, Doflamingo also noticed a girl named Violet (Her other name is Viola and she is the second daughter of the old king of the Kingdom of Dressrosa) because she was also very beautiful, which pirate doesn't like beauty, right? He also only notice to Violet because of her beauty so during that time Doflamingo and Violet also had an incomplete relationship...Doflamingo didn't worry at all until Crocodile started contacting him less. Doflamingo feels something strange from Crocodile's side and he thinks Crocodile also discovered his complicated relationship with Violet so he is trying to piece together the relationship with Crocodile...he hopes that Crocodile won't be angry with him
Crocodile's Den Den Mushi is carefully preserved by Doflamingo. Only Sugar often visits Doflamingo's room, so that lovely girl knows that her young master is keeping Crocodile's Den Den Mushi
Doflamingo called Crocodile using Den Den Mushi but Crocodile didn't pick up, making Doflamingo a bit disappointed but he quickly returned to normal when Crocodile picked up, he really wanted to invite Crocodile to Dressrosa kingdom to celebrate so maybe he's sure he'll find the right words
Crocodile, I'm glad you picked up my call because today I have good news so I'd love for you to join me
