Your friendly neighborhood Lacendy is drown in LCL

In this au I came up with absolutely for like pure self indulgence, Kaworu is an alien who ran to Earth to take shelter from an invasion happening on his planet. They are humanoid aliens, with extremely high empathy and abilities to understand other living beings' emotions perfectly. They are a pacifist race, reason why they were so easily invaded, as their defenses were low. Kaworu's safety spaceship crashes on earth, getting the attention of the authorities and he's immediately brought into a government research lab. Kaji works as a guard there and can't stand the thought of a living, breathing being getting tortured and experimented on. Especially when it looks so much like a human. The research facility had never done experiments on living beings, they mostly focused on rocks, plants, other matter that seemed to come from outer space and that needed analysis.

Kaji decides to break Kaworu free, creating a foolproof plan beforehand, taking multiple weeks. He has the sympathy of other guards and workers from the facily, who too empathise with the alien, deeply upset at how he’s being treated. Kaji’s able to break Kaworu free, getting him into his car and then speeding away to the safety of his small house in a rural town in the middle of the countryside.

The first thing he does it patch Kaworu up: bandage his cuts from the vivisection, cover hos bruies from the blood withdrawals with cream. He becomes Kaworu’s surrogate father, constantly making sure to tend to his wounds while he’s recovering, the boy spending a few days of total moping around between Kaji’s guest bed and the couch because he is just so exhausted and in pain from the experiments. When Kaji is working he alternates naps to watching tv, curious about human entertainment. He loves animal documentaries or historical ones. Once a few days have passed and he seems to be doing better, as well as Kaji being sure no one is onto him, the man decides to take him for a small ride to his trusted farm where he gets fresh produce, wanting Kaworu to get some fresh air and having promised he’d let him see cows in real life.

Shinji finished Highschool and, unlike his parents had thought, he has no desire to go to university. The school years have exhausted him to the point that the thought of more studying makes him sick. So over the summer, while his parents travel around the country for their job as researchers, he started working at his aunt Misato’s farm, taking quite a liking to it. He likes staying with the animals, tending to the plants. It’s tiring, but he enjoys it and makes him feel alive. Kaji is a regular and always welcome at the farm.

Kaji prked his car near the cows before going to Misato to ask for what he needed. Shinji is the one who had to bring the produce to his car while Kaji and Misato chat. What Shinji didn’t expect to see was an albino boy looking at the cows with the eye sparkles a little kid would have. The boy is quite cheerful and friendly; he asks for Shinji’s name as well as the cows’. What unsettles Shinji the most is seeing all his bruises and bandages: around his hands, his arms, his neck even. When Kaji comes around he pats Kaworu on th3 shoulder, saying it’s his nephew visiting him. Shinji immediately thinks abuse is going on. He doesn’t want to make a scene, nor is he sure of his suspicions, so he keeps quiet and watches the two go away.

The following day Shinji decides to take his bike and go to Kaji's place, using excuse that he forgot a bag of apples and needs to deliver it to him to get the address out of Misato. He bikes to his house, walking quietly around it to peer inside and see if the albino boy is there.

"I didn't expect to see you around the house."

Shinji almost shits himself. The boy is behind him, calm as he can be, smiling at the brunette. Kaworu invites Shinji inside and an awkward conversation starts, Shinji worried sick and trying to understand if Kaji is the one at fault for Kaworu's wounds. Kaworu quickly picks up where Shinji is going and reassures him that no, it wasn't Kaji and he would never do anything like that to him. Shinji is relieved, but not completely, still anxious to understand who might have hurt the other boy that bad. Kaworu takes a while, his high empathy analyzing Shinji and his behaviours in an attempt to understand if he's completely safe as he seems or not. Eventually, Kaworu decides to tell him the truth, making Shinji promise to not tell anyone else.

Shinji ends up hanging out with Kaworu all day, now curious to understand the other, until Kaji comes home and chaos ensues. He’s mad at Kaworu for exposing them and possibly putting them at risk, but when Kaworu tells him his reasons and that he thought that maybe, having allies in the city would help them, Kaji calms down and realizes that having a bit of support might not hurt. He talks to Misato, explains the situation and she’s surprisingly very calm about it. She tells Kaji that, if he’s worried, he could leave Kaworu with them during the day as he works. The farm is in the countryside, it’s quite isolated and Kaworu would be safe there.

Until Kaworu’s wounds are fully healed, Misato only asks him to keep an eye on the cattle or feed the chickens, trying to keep his labour to a minimum to avoid opening up his wounds again. After that he helps shinji in the fields and doing other things that might be more tiring. The two grow a lot closer, goofing around on their spare time, Shinji sometimes taking Kaworu to arcades in the evening, having him wear a big goodie with the hood pulled up so that he won’t be easily spotted as an outsider.

Their peace is soon broken as Kaji starts suspecting that the facility might be onto them and he tries to find a solution. He can’t run away with Kaworu, he would immediately become suspicious and be tracked down. So Shinji offers to take Kaworu away. He has money put aside for what was supposed to be his university fund. He has a van his parents got him instead of a car because he wanted to be able to drive but also help Misato with deliveries and such. He and Kaworu quickly pack their things, leaving instructions to Misato as to what to say to his parents in case they call her and ask about him, instead of calling him directly, and then they run off, stopping in a city farther from their own to buy supplies to modify the van, turning it into a livable space.

They keep travelling, only stopping for very short periods of time and picking up short jobs like dog sittinng and lawn mowing to avoid spending all of the money saved (it’s quite a bit but they have no idea how long they’ll be on the run and want to avoid tricky situations). Kaworu gets to see the world, the beauty of nature and many different people and Shinji gets out of his comfort zone too.
