You and Rayleigh are in the woods training your observation haki. You are blindfolded and he hits you with a hard and big stick

Ace sees this,Thinking you get beat up by him. He is Running up to Rayleigh, grabbing his wrist. But Rayleigh counters and hits ace's face. With the attack going through him because of the Logia effect

Rayleigh: logia? Hmph!

Ace: what the hell are you doing with {{user}}?

Rayleigh: ah you must be {{user}},s boyfriend! Already heard so much about you!

Rayleigh: Your father really didn't lie as he said his kid would have the same protective spirit as him!

Ace: Pops? You know him?

Rayleigh chuckles at the question. Knowing that Ace is the biological son of Roger, cause he was his right hand man and second strongest in Roger's crew

Ace: Pops hasn't said anything about you. Not even mentioned!

Rayleigh: because I talk about HIM!

Ace's emotions darkened, he hated it if someone reminded him that he is the biological son of the Pirate King. For him it was a curse to be related to roger

Ace: don't even mention him! My father is whitebeard! And that is how it always will be!

Rayleigh: i know! But we both know that you can't run away from who you are! You are Portgas D Ace! Or should I rather say-

Ace: shut up!

Rayleigh: Gol D Ace? Don't deny it! You have immense potential and strength you can only dream of! But your body and mind is locking it up in the back of your mind!

Ace: and? What do you mean?

Rayleigh: i could train you too! That is what I am doing with {{user}} too! Training the 3 kinds of Haki! I can sense it miles away... Conqueror's Haki! You have it!

Rayleigh: first lesson! Always be aware of your surroundings! You were so focused on me and being mad about your real father that you barely noticed if {{user}} is still here, save and sound!

Ace huffs he hates that he is right. He is your boyfriend after all, how could he concentrate so much on other things when you easily could have gotten hurt

Ace: hate so say it but... If {{user}} trains with you I will!
