Welcome to DBZ Love Garden

The weather was extremely hot, the trees were very dry like the earth, which was full of cracks, you could tell it had not rained in that place for a long time. A little, dark-haired, half-saiyan boy walked under the strong sun of that day, looked up, shielding his eyes with his hand to prevent the sun's rays from dazzling him, and he could see a flock of birds known as vultures and other scavenger birds flying around the area and that did not stop making noise, looking down he could see a small bird perched on a sword that was very familiar, wait a second... it was Mirai Trunks sword! And that little bird was perhaps a representation of the time traveler who had long known and had become his best friend, Gohan wanted to approach to the bird but he just took a few steps when the animal took flight away from him.
"Wait!" Gohan cried, running towards the bird “please come back where you are going? Come back!... come back ...”
Now the scene changes drastically to the moment when Mirai Trunks prepares to return to his timeline, the bird that Gohan had been chasing before, landed on the young lavender haired teen time machine, there was no one else around except for a few mountains in the distance, only Gohan and Mirai Trunks were there, the younger half-saiyan was sad, because his best friend would leave and he would not know when they would see each other again.
"Please, don’t leave..." Gohan said, on the verge of tears "whatever you do, don’t leave because... because I love you” the little boy came closer to the time traveler and hugged him with all his strength, with the intention of not wanting let him go, Mirai Trunks was surprised a little but then he take back the hug with a lot of tenderness, transmitting his affection and friendship to the kid “I love you, Trunks and I will always love you”

****

Seventeen years have passed since that day, Gohan patiently waited for the time traveler to return someday but as time passed, he grew up and made his life normally, Gohan gradually lost hope and the illusion of seeing him again so he decided to temporarily forget that, he followed the dream that his mother had imposed on him since he was little kid, he devoted himself to studying, he aisle himself from the martial arts in order to become a scientific scholar, not only that, in high school he met a cute girl named Videl Satan, who was daughter of the martial arts fighter champion, Mr. Satan, with her he got married and they had a daughter who they called Pan, following the family Son tradition they are to call the children with names of food, strange thing in Gohan, because the name of his little brother had another meaning. Suddenly he awake from that strange dream, breathed raggedly, he did not know what to do, every day that dream became more and more frequent, tormented him, could not find the reason why he had that dream but something was sure, he would find out the meaning of that dream and why tormented him all the time.
"Gods, I had that strange dream again..." Gohan thought, trying to calm down, tears coming from his eyes, why was he crying? Was that dream so strong that it affected him when he woke up? He let out an anguished sigh and after calming down a bit, dried his tears, got up from his bed to be able to dress normally and start the routine he did every day before going to work.
After drinking a cup of coffee thinking about what he had seen in the dream, Gohan put his backpack around his shoulder, left his house and started walking the path he did every day to go to the college where he worked, before going, he went through a stand to buy a newspaper, while he read it he looked at his watch, there were still a couple of hours left for him to go to work but that was not the reason why he had to get there early. He kept the newspaper in his backpack and resumed his way to the college but something made him stop, because he felt a very familiar ki not far away from where he was.
"What?" Gohan thought, he would recognize that ki even if it was kilometers away or scattered among other ki’s “no... it can’t be posible!... it can’t be him”
Gohan teleported to the place where that ki was so well known to him, came to a mountainous area, looked around and could see the time machine that had brought a certain lavender haired warrior to his life seventeen years ago, he descended towards the machine and could see Mirai Trunks unconscious through the glass dome of the machine, seeing him in that state, the worry and anxiety began to invade him, he hit the glass of the dome and called him by his name waiting for him to react but that never happened. He calmed down a little and remembered that seventeen years ago, Mirai Trunks had explained to him that in the machine there was a button that when it pressed, the glass dome was opened, he quickly checked the machine until he found that button, he pressed it and just the glass dome opened, he pulled Mirai Trunks out of there, carrying it in his arms, he flew as fast as he could to Capsule Corporation, it was the most logical thing he could do and maybe Bulma could help him.

Later in Capsule Corporation, Mirai Trunks lay unconscious in a bed from one of the many rooms of the huge yellow dome-shaped building, Gohan and his father, Gokū were there, Bulma had entered the bedroom with a tray of food left there for the time traveler, the three of them were very worried about him, they did not know what had happened to him or how he ended up in that state. Gohan thought about what they could do to help him until an idea came up in his mind.
"I have to look for the senzu beans" Gohan said "it's the only way we can cure Mirai Trunks"
“I think it will be faster if I go to look for them” Gokū said, Gohan nodded and Gokū teleported to go to find the senzu beans leaving Gohan and Mirai Trunks alone in the bedroom. The adult half-saiyan approached a little more and looked at his best friend of an alternate future who lay unconscious in that bed, he pressed hard one corner of the sheet, anger attacked him, it hurt him to have to see Mirai Trunks in that situation, he still did not understand what was happening in his timeline to be in that condition and have had to travel to the past, there was an enemy so powerful that even Mirai Trunks couldn’t face?
“Damn it!” Gohan began to remember when Cell attacked the lavender haired warrior with a single blast of energy, killing him instantly, they were lucky to be able to revive him with the dragon balls but now he did not know if he was going to survive this time, he just wait for his father to return with the senzu beans soon, he tightened his grip on the sheet and his knuckles turned white from the pressure he was exerting on the fabric “don't worry, Trunks. This time I will not let anything bad happen to you, I will be here to help you... I will protect you!”
A few minutes later, Gokū returned to Capsule Corporation with a bag full of senzu beans, he approached the bag to his son who took it, untied the small rope that closed it, took out a bean and gave it to the time traveler. When Mirai Trunks swallowed the bean, he felt his body begin to feel better, the bean was repairing all the damage that his recent enemy in his timeline, Black Gokū, had caused him. He woke up and got up sitting on the bed, looked at the bedroom where he was in, looked closely at his hands and arms which were previously full of blows, wounds and scars from the beatings he had received from Black Gokū.
“Where I am? When do I get here?" Mirai Trunks asked himself, but when he saw Gohan sitting next to him, he decided to put his questions aside, because he realized that he was in the past, or rather, on a different timeline than the where nothing of what was happening to him happened on that timeline because he saved Gokū's life a long time ago “Gohan!”
Unexpectedly, he rushed towards the now adult half-saiyan to hug him tightly, Gohan remained static for a second but then he take back the hug with care not to hurt him, Mirai Trunks closed his eyes, gods, he had missed him too those seventeen years away of him and now that he had seen him again, he did not intend to let him go again, he wanted to be with him again like in the old days, feel his warmth, enjoy his company again, his friendship but above all, his affection but now was not the time for that, because his timeline was on the risk of destruction and they had to do something to stop Black Gokū.
