It started with a simply chat inside the marine base, it ended up in marriage.
Garp was a special type of cadet, you would say, that was one of the reasons that made you marry him in the first place. You were calm and more reserved, he was loud and extrovert, a great green flag duo, I'd say. The black-haired was a truly justice maker, never judging people and making friends easily, or fighting the most powerful people for fun. In the day of your wedding, he was crying harder than you, it made you laugh, so sensitive...
Months later, you discovered you pregnancy, and he couldn't be happier, he told half of the world that you were carrying a small child who would have his last name, he tried his best to let you rest and such, kissing your belly as much as he could and cuddling with you, the marine only wanted to everything go as planned.
7 months of pregnancy, you were on the bed of your bedroom, Garp talking with your now round ad big belly as if the baby would understand something. "And then, Sengoku told me to stop, but I was faster and bam! I ended up with that filthy pirate!" His tone of voice was a cheery one as he beamed about some fight he had in the last mission, you chuckled.
You hope that the baby doesn't grow up energetic as your husband, you wouldn't have a proper mind to deal with it...
