[Crossover] The Good Dad's Guide

Sakuta, a member of the Whitebeard Pirates, transmigrated. As a pirate who inherited Pops' fine traditions and even improved on them, the moment he landed, he took hold of the hand of a passing black-haired boy and said with deep affection, "Will you be my family?" Looking at the handsome young man before him, Geto Suguru: "???" He'd thought he'd just run into a lunatic. Who knew the guy was serious?! When they were out on a mission and couldn't get a meal, the young man immediately produced a lavish feast for Geto Suguru. Gojo Satoru: "...A crazed admirer?" Geto Suguru: "..." When they were attacked by the strongest Heavenly Restriction user at the Tombs of the Star, the young man appeared like a ghost, charged into battle with a kitchen knife, and fought the Heavenly Restriction user to a standstill. "Don't be afraid! Daddy's here to save you!" Ieiri Shoko: "Case solved. He wants to have an illicit affair with you. His tastes are pretty open-minded." Geto Suguru: "..." When some unknown brain in a jar tried to steal his body, the young man stabbed it to the ground with one slash. "You dare try to steal my person? Who do you think you are?" Geto Suguru: "...He really is after my body." So when everything was finally over, Geto Suguru thought numbly, maybe he should just give in... Who wouldn't get confused by that kind of pursuit? At any rate, he'd been thoroughly swept off his feet. Who could have guessed... The young man looked genuinely baffled. "But I really just wanted to be your dad!" Geto Suguru: "?????" - After reflecting on his failed approach to winning people over, Sakuta, using the name Sakuta, resolved to change his invitation strategy. He'd be a dependable, mature elder! Then, at some point, a strange young man appeared at Nakahara Chuuya's side. Warm, cheerful, and unfailingly considerate, he looked like a guiding light on Chuuya's journey through life. When enemies came, he fought alongside Chuuya. When a companion betrayed him, he took care of the traitor. When a better future came into reach, he carefully helped Chuuya plan and find the path that suited him best. Nakahara Chuuya's heart skipped a beat. Two years later... The young man called him to Tokyo Bay. As fireworks bloomed against the night sky, Chuuya heard him say, "...Would you be willing to call me Pops?" Nakahara Chuuya: "...???!!!" After four consecutive failures, Sakuta gave up. But the terrifying part was that everyone he'd tried to win over showed up at his door together. Sakuta: "..." What a hopeless world! Theme: Three parts destiny, seven parts hard work! Only those who dare to fight can win!
