Disclaimer: I don't own Naruto or My Hero Academia or Happy Sugar Life

Hey everyone it's me so this fanfic is a Shotacon and a Yaoi also this fanfic's storyline has to do with the anime Happy Sugar Life if you haven't seen the anime I suggest you do since it'll be kind of hard to follow and understand the story and etc also in this fanfic Katsuki is a Yandere so yeah that's all I wanted to say please enjoy :)

"Katsuki Kun I love you so much please will you go out with me?" A girl with long brown hair and wearing the UA school uniform asked him as she was blushing and smiling at him while handing him an envelope with a confession letter inside.

Katsuki takes the note and he looks at it for a few seconds silently and then he destroys said letter with his quirk. "FUCK OFF EXTRA! I ALREADY HAVE SOMEONE WHO I HAD GIVEN MY HEART TO ALREADY SO PISS OFF!" He yells at her while he glares at her hatefully and coldly and then he walks off heading to his job at a cafe which was a cosplay cafe where girls dressed up like cat maids.

All of Katsuki's classmates heard what Katsuki said and they're jaws dropped in shocked. They wondered who could ever be the one to have stolen Katsuki's heart. "Whoever it is they must have the patience of a saint." Denki says making everyone else nod their heads in agreement.

At the cafe Katsuki was in the changing room for the male employees as he changed into his work uniform which was a white short sleeved shirt and a black vest and a light blue tie with a yellow pin on it and black work pants. Katsuki worked as a waiter inside the cafe and a body guard for the female employees since the male costumers seemed to enjoy being handsy with them and mistaken the cafe as a strip club and have even asked for a few female employees to sit in their laps and etc.

But when the moment they saw him they automatically stopped since with one heated glare from him makes them nearly wet their pants. After changing into his work uniform Katsuki leaves the locker room and goes out to work as he worked his classmates from school came. "Bakubro when we're you going to tell us you got yourself a lover?!" Kirishima asked him as he sat at a table with Denki and Mina and Shero.

Katsuki blushes a bit while glares at him. "That's none of your business shitty hair, but...if you must know we had just moved in with each other and are now living together." Katsuki tells them as he then noticed Denki about to grope one of the waitresses but he stopped when Katsuki sent him a heated glare and made sparks appear in his hands to let him know he will not hesitate to use his quirk on him.

Katsuki then rolled his eyes and goes back to work just wanting to get his work shift over with so he can go home and be with his beloved. After work finally got out for him Katsuki darts home right away as he arrived at an apartment building and smiles and blushes while he stares at it. "I'm finally home now...my cute little fox." Katsuki thinks to himself while he stares at the one apartment with lights on where his beloved was waiting for him.

A few seconds later Katsuki arrived at his home there he unlocked the door and enters inside and smiles. "I'm home." Katsuki says and there right in front of him sitting on some steps near the front door was a little boy with golden blond spiky hair big innocent blue eyes that were full of so much innocence he had tan skin and he wore a orange hoodie with cute Fox ears on the hood and black shorts and he had on white socks and he was around eight years old but he was small for his age and he had cute whisker like birth marks on his cheeks.

The little boy's name was Naruto Uzumaki and he was Katsuki's beloved. Naruto smiles the biggest and most innocent at the teenage boy. "Katsu Kun! Katsu Kun!" Naruto says happily and innocently and hugs him making Katsuki smile and blush and hugs him back. "So sweet...such a sweet smell." Katsuki thinks to himself.

They both pulled away from each other from the hug and Katsuki bends down to Naruto's level and strokes his soft blond hair. "Naruto chan, we're you cold waiting for me at the front door?" Katsuki asked him smiling a soft warm smile at the small boy being rewarded with his usual cute innocent smiles. "Nope because I wanted to welcome you home Katsu Kun." Naruto says in a child like innocent manner making Katsuki smile and hug him again. "Naruto chan you're so cute." Katsuki says to him snuggling close to him.

Later on they were both in the bath tub together as Naruto was playing with a rubber duck. "Bubbles, bubbles." Naruto says happily as he was sitting in Katsuki's lap while they took the bath together, Naruto then looks at the duck watching it float and he tilts his head to the side like a fox. "Katsu Kun, how does the ducky float?" Naruto asked him innocently and curiously looking at him making Katsuki frown and think for a few moments he wanted to find the best way to explain it to him in a way a child would understand.

"Hmm well the water it's helping it float." Katsuki says to him making Naruto feel satisfied by the answer and smiles brightly at him. "Wow Katsu Kun you're very smart you're like a professor." Naruto says to him happily and then he turns to face Katsuki and he holds the rubber duck in his hands. "Katsu Kun I'm going to be like your water so I can always help you so you won't be sad and lonely." Naruto says to him happily and innocently making Katsuki blush and smile at his cuteness.

"Naruto chan is just too cute and pure for his own good." Katsuki thinks to himself while he began to wash his chibi uke's hair. After they were done with the bath Katsuki grabs a white buttoned up shirt and begins to dress Naruto in it which was what he wore for bed while he himself wore a black tank top and sweat pants.

After putting it on him Naruto yawns cutely and rubs his eyes looking tired making Katsuki smile at him. "It's okay Naruto chan let's go to bed now." Katsuki says to him gently and warmly. Naruto looks at him and smiles and nods his head as Katsuki picks him up and carries him to the bedroom there they both laid down and falls asleep with each other while Katsuki holds him close while he also holds Naruto's small soft hand in his own enjoying his warmth.

They usually did vows before going to bed but he didn't pressure Naruto into doing them tonight since he knew that Naruto was very young and got tired when he stayed up too late. "Oh well...we can do it tomorrow after I get home from my new job which I'll be starting tomorrow." Katsuki thinks to himself smiling to himself and then he allowed sleep to take over him.

The next day Katsuki was dressed in his school uniform as he was at the front door tying his shoes while Naruto watched him silently he was wearing his usual outfit as he didn't seem like he wanted him to leave. Katsuki turned to Naruto and smiles an apologetic smile at him. "Sorry Naruto chan, I'll be home a little late today since I'll be starting my new job today but when I get home we can spend time together okay." Katsuki says to him gently, Naruto then smiles and hugs him.

"It's okay I know you're working hard for me so I'll stay here and pray so we can be happy together forever Katsu Kun." Naruto says to hims happily and innocently making Katsuki blush and then smiles and then he bends down to Naruto's level and hugs him. "Thank you Naruto chan, I'll be working hard for the both of us." He tells the small blond child and then he leaves for school.

After school got out he goes to his new koi which was called the Princess Imperial Palace, Katsuki quickly settled in and got to work right away the manager seemed very kind and all the other employees whom were both female and male seemed to like him too he even got the interest of a certain male employee named Taiyo.

Later on after work Katsuki was at home wearing his usual sweat pants and tank top as he was sitting on the couch talking to Kirishima. "So Bakubro how's your new job going? I heard that the manager is pretty and kind." He asked him on the other line while Naruto was standing in front of the tv which was in a channel they didn't have.

"It's going well shitty hair everything seems fine as long as nothing fucking annoying happens." Katsuki tells him feeling a little annoyed he didn't feel like talking right now and just wanted to spend time with Naruto although at the same time he knew his friend was probably just concern for him and was just trying to look off for him and etc since he was now working two jobs. "I know I'm working so much but that's only because I want to support my boyfriend and I, speaking of which I have to go I'm actually fucking tired and want to spend time with him before going to bed." Katsuki tells him making Kirishima laugh in a sheepish manner.

"Oh right sorry my bad well have a good night see ya tomorrow." Kirishima tells him and hangs up. Katsuki then noticed Naruto was tapping the tv a bit since he didn't understand that they didn't own that channel which Katsuki noticed and he walks over to him and placed a hand on his shoulder and smiles at him. "Naruto chan we don't have that channel." Katsuki tells him making Naruto turn to him.

Katsuki sighs a little he knew he had to work again at his new job the next day he was okay with that and his new job but he just hopped nothing annoying happens. Afterwards Katsuki and Naruto go into a different room and they said their vows with each other and go to sleep. The next day at Katsuki's work place Taiyo approached him and tells him that he really likes him and wanted to go out with him.

Katsuki frowns staring at him. "Umm I'm sorry you can tell me your answer after work." Taiyo tells him but Katsuki stopped him. "No I can't...I had already given my heart to someone else." Katsuki tells him and then he goes back to work not knowing that the manager was over hearing the entire conversation. Later on after work ended Katsuki was on his way out when he noticed Taiyo going into the office with the manager making Katsuki frown at this as he then continued his way out. The next day at work Taiyo didn't come into work at all.

The manager then asked him to do some work overtime since it was his fault that Taiyo stopped coming to work since he rejected him. Katsuki however felt she was lying but kept silent about it and nods his head begins to work over time. After he got out of work it was late at night and Katsuki returned home to find his little beloved near the door wrapped in a white blanket as he had fallen asleep waiting for him to return home. Katsuki goes over to his sleeping lover and sits down on the floor and holds him gently in his arms.

"Katsu kun." Naruto says in his sleep as Katsuki grinds his teeth a bit. "I can't keep living like this if I do...I'm going to go fucking insane." Katsuki thinks to himself as he had a crazed look in his eyes but his expression was blank. This goes on for awhile and when pay day finally arrived Katsuki looked at his pay check and frowns at his payment. He saw he wasn't paid for the hours he worked for. "Manager can I talk to you for a moment?" Katsuki asked her getting her attention.

A few moments later Katsuki was back to wearing his usual school uniform as he was now standing in the manager's office. "Why was my pay cut? I had worked all the hours like I was supposed to." Katsuki says to her and then she smirks at him. "Oh no that's the correct pay, you must understand why right Bakugo san?" She asked him and then grabbed his face and glares at him. "You are just too handsome, ever since you came here everyone even the boys began to pay so much attention to you, you've caused nothing but problems for me since you arrived here at my kingdom of love." She tells him and then shoves him making Katsuki grind his teeth and clench his fists. "Love?" He says to her as he then remembered something...something from his childhood..something he learned from his mother whom when his father wasn't around she invited men over and slept with them and let them do whatever they wanted to her she would even go to male stripper bars and bring him with her and would she tell him that this was also love

Katsuki was silent as he then turned his face towards the manager. "You're wrong, you shouldn't be going after underage kids you bitch." He tells her in a cold tone his eyes were a dark red making the manager confused. "I saw it happen I know you brought Mitsuboshi san back here, and I know how you forced himself on him the stench of this room makes it pretty clear of the events that happened back here." Katsuki tells her making her turn pale white while Katsuki's gaze turns towards a closet. "Tell me, did it really stung that bad? To have everyone turn their attention towards me than you?" Katsuki asked curiously as he takes out his phone without her noticing and he pressed the record button to record a video of her and then he recorded her entire confession of her admitting that she had raped Taiyo.

Afterwards he showed her the video make her shake with fear as he grabs her by the hair and glares at her hatefully. "Pay me what I'm owed bitch or else your entire so called kingdom of love will crumble before your very eyes." He tells her coldly while he looked at her with pure disgust. After he let go of her hair he opened the closet revealing Taiyo whom was naked and tied up and gagged as he was silently crying. "Beware of all women Taiyo, since they all have a sick desire to keep people to themselves." He tells him as he unties him and helps him dressed and then he leaves.

On his way Katsuki felt a sick feeling in his stomach and a horrible bitter taste in his mouth he was glaring at everything up ahead as he was grinding his teeth. Katsuki then arrived home and unlocks the door and is greeted with a warm innocent smile from Naruto. "Katsu kun!" Naruto says happily making Katsuki smile and hug him while he feels the sick feeling in his stomach going away.

"Naruto chan, you stayed up so late aren't you tired?" Katsuki asked him making Naruto shake his head no. "No I didn't want to go to sleep without saying welcome home to you Katsu kun." Naruto tells him as he pouts making Katsuki blush and smile as he snuggles close to him and kisses his lips gently. A few minutes later Naruto was in their shared bed fast asleep while Katsuki smiles and watches him sleep for a few moments until he stands up and quietly leaves the room and walks towards a door with a few locks on it.

Katsuki looks at the door silently his expression cold and blank as he begins to unlock the door and enters inside once inside he leans against the door and smiles at three trash bags which contained the chopped up pieces of a rotting corpse as the whole room was stained in blood and it had a bloody saw on the ground. "Thanks for your apartment it's so nice and comfortable." Katsuki says to the the three trash bags while a memory flashes into his head again with someone trying to strangle Naruto and with him killing the person whom tried to hurt his chibi fox.

Katsuki rubs his chin and smirks to himself. "This is no good these things they are simply in the way, oh well I'll just have to throw it away now won't I?" He says to himself while he smiles and placed a hand on the place where his heart is. "I should really thank you, after all because of you I now know what this wonderful feeling is and now I have to do everything I can to protect it and make a nice lovely castle for me and Naruto chan to live in together happily forever." Katsuki says to the bloody bags talking to them like they were a dear old friend of his. Katsuki smiles and looks at the ceiling and blushes. "Welcome home, my happy sugar life." Katsuki thinks to himself happily willing to do anything at all to keep living this life he had so far built with Naruto.

And he was going to make sure no one takes it away from him.
