I literally had a dream about this. It wasn't with KHR with it was for a tv show, but since I rarely watch that show, I decided to use it for KHR. I realized that there are a few stories where there Tsuna is getting married or having kids or some other major event and he receive advices and stuff from other people, but I felt, despite not liking Iemitsu, that he was the only one who could give this sort of advice to Tsuna.

So I hope you guys enjoy this.

The One Time Tsuna went to Iemitsu for Advice

Balloons, confetti's, food, drinks, and about thirty or so men filled up a ballroom. They were all laughing and having fun because for once there was a reason to be happy. At the moment they were in a middle of having a bachelor party something they didn't expect from the young man in white, Tsunayoshi Sawada. While all his guardians and close friends found their wives and lovers, Tsuna denied himself of such happiness and they all wondered if they were going to have to set him up for a loveless marriage, but to their shock and happiness, he found the one.

Amethyst Carter was no doubt a strange woman, with her hair always in a shocking new color and is always hopping around everywhere. She and Tsunayoshi met under a strange circumstance and had an even stranger second meeting, but that was a story for another day.

Tsunayoshi was happy for the occasion, he was happy that he wouldn't be alone anymore, but he was wondering if the marriage would last. He and Amethyst were as different as they can be when it came to responsibility. They don't ever see eye to eye when it comes her dropping her occupation to stay closer to home. She never seem to understand that she was marrying a mob boss and could be used as hostage as a liability, though he doubt anybody could catch her, but her luck would bound to run out one day. They both got into an argument just the other day about her job and her listening problems.

He sighed and looked around the room. He saw Dino, he had a wife and a kid now. He saw his father figure Reborn in a corner with his best friend, though those two would never admit it, Colennello. Colennello was married to his sweetheart Lal and Reborn was in a relationship he was sure of it. All in all everybody was matched up with somebody, but none of them been married long enough to give him advice about marriage except for one person. That man, his father, sat in the corner laughing and joking with his former subordinates. He wished that Nono didn't passed away so soon, he could've went to him for advice, but maybe that his way of telling him that this was a talk he was meant to have with his father not him.

Iemitsu have been married to his mother for twenty-nine years. Even now Tsunayoshi still didn't understand why his mother didn't dump him for a better man, but she was so happy, so he had to know.

Moving from the corner he glued himself to since the beginning of the party, he weaved his way through the crowd and made his way to his father who looked at him curiously just like everybody else at the party did.

"Can we talk?"

There was an eerie silence between the two as they both stood awkwardly in the Vongola prized garden, looking at different parts of the garden just to avoid looking at each other gazes.

"You've been married to mom for twenty-nine years it would be a stretch to happily, but nevertheless twenty-nine years. How did you make it work and how could I do the same?"
Iemitsu might've not been the best father, but he understood Tsuna was never the one for simple answers. That child had a thick head and you had to work your way around it. Iemitsu thought about his beloved wife, Nana.

"Tsuna, I'm going to take my pickaxe and trash the entire ballroom causing indescribable amount of damage."

Tsuna shot his father a weary look. "Seem like a pointless thing for you to do."

"That's the same thing I can say about your soon to be union," Tsuna glared at his father, but that kind of described how he felt at the moment. He and Amethyst fight often to the point he wonder why he even asked her to marry him. "You and Amethyst fight a lot about many different things, you two don't see eye to eye and you guys have very different opinions. A lot of people like you guys would've dumped each other to find somebody who shared the same views, but in the end that would've been their own undoing. So why, why do you two stay with each other despite of that?"

Tsuna thought about it. He loved Ame. He loved her very much and he wouldn't dare let her go.

"The thing with marriage, a lot of people think that after they get married and say their vows, that it's going to be smooth sailing from there and there would be nothing to worry about. They're wrong and I made the mistake to think that way. Marriage still requires a lot of work, it doesn't get any easier, but it doesn't have to get any harder. You're still going to have your petty arguments, something about your spouse is still going to annoy you, and you're going to have to make unwanted adjustments and compromises and decisions that could hurt the other even if it's for their own good, but that's what it means to married."

Tsuna never thought of it that way. He wasn't naïve enough to think that once you get married that you're automatically will be happy for the rest of your life, but he thought all the problems before your marriage would kind of disappeared, but that still didn't explain why mom and he were still married.

Iemitsu golden eyes met with his son brown ones. "You're still wondering why your mom and I are still married, let me tell you it wasn't easy and I had to do a lot of groveling before I can even get hug or kiss from your mom again. But let that be a story for another day." Iemitsu said making his way to back to the bachelor party.

That man made his mother cry, he practically abandoned both of them, but he could still make his mother smile so happily. There were a lot of things that didn't make any sense to him, marriage being one of them. He could be stubborn and ignore everything his father told him because what can a man who hasn't been with his wife through all the hardships she had to face alone, tell him. But Tsuna ended up taking his advice, his words of wisdom to heart.

That's how he was able to stand at the altar with Amethyst and Reborn, as the priest, and a few witnesses and marry her. The wedding was a quiet and happy event, their marriage was a wreck, raising their children was even worst, but growing old with each other made him realize it was all worth the stress and the aggravation. He was happy.
