Liam's football career had become stuck on the bench.
At the age of twenty, after great effort, he had signed a professional contract with Westhall FC, a team in England's Fourth Division. He believed that once he turned professional, everything would start going his way. However, two years had passed, and he had only managed to play in ten matches. With each passing day, his standing within the team weakened, and his chances of stepping onto the pitch grew slimmer.
Due to the strict hierarchy within the team, Liam was often subjected to poor treatment. Despite this, he attended training sessions regularly and did everything he could to improve himself. That day was no different. After finishing training, he planned to head to the locker room and take a shower.
As he was taking off his top, he heard a voice.
"Liam."
Standing in front of him was Coach Lydia. Her short, tight skirt accentuated her body lines clearly. Even though Liam tried not to stare, his eyes were drawn to her against his will.
"I called you. Aren't you listening?" Lydia said.
Liam pulled himself together and replied,
"Yes, of course. What did you need?"
His voice came out with some difficulty. Although Lydia was physically attractive, her personality made Liam dislike her deep down.
"There are some documents left on the field. Go get them. And don't scatter them."
Despite being a player on the team, Lydia frequently used him for menial tasks. Though irritated, Liam kept quiet, knowing he needed to hold onto his place at the club.
"I'll get them right away. Please sit here."
After showing her a clean spot in the locker room, he headed toward the field.
Once he had the documents, he hurried back. He wanted to shower and finish everything as soon as possible. As he went down the stairs, his foot slipped. He lost his balance and fell hard to the ground.
He cried out in pain.
When he slowly opened his eyes, he saw a blurry silhouette in front of him. Lifting his head slightly, he recognized Lydia's face.
"How long are you going to keep staring?"
Her sharp voice startled him.
"I wasn't staring on purpose. I'm sorry."
Looking around, Liam realized he was in the infirmary. Lydia had brought him there after hearing his scream. She was sitting in a chair across from the bed.
"All you had to do was pick up the documents, and you couldn't even manage that," she said irritably.
After complaining for a while, she left the room. Even though she was angry, the fact that she had waited for him to wake up gave Liam a strange sense of comfort.
A short while later, the club nurse arrived. After checking him, she said there was nothing serious—just a mild concussion. She advised him to rest a bit longer and then left him alone.
The moment he was alone, Liam felt an intense pain start in his head and spread throughout his body. The pain continued nonstop for about five minutes.
"Do you accept fusion with the Lust Fusion Device?"
The voice echoed directly inside his mind. The word lust made him uneasy, but his curiosity got the better of him.
"I accept."
"Initiating fusion with the Lust Fusion Device."
The pain surged through his body once more, stronger than before. After a short while, it suddenly stopped.
"Fusion complete.
User: Liam White
Gender: Male
Age: 22"
A translucent screen appeared before his eyes.
"You are now the user of the Lust Fusion Device. You may ask me any questions regarding the system."
Liam couldn't hide his shock.
"Who are you? And what is this Lust Fusion Device supposed to be?"
"An ancient civilization once advanced using high-level technology such as the Lust Fusion Device. However, they were destroyed by a meteor shower. The device that has fused with you is the last remaining example of its kind. I am the advanced artificial intelligence connected to it. My role is to guide the user."
Just as Liam was about to ask more questions, the door opened. Lydia entered the room. Panicking, Liam forgot to close the screen—but quickly realized that Lydia couldn't see anything. Only he could.
"Why do you look so tense?" Lydia asked.
"You surprised me, that's all."
After sitting down across from the bed, she continued,
"There's training tomorrow. Since there's nothing serious, I expect you to come as usual."
Normally, she would have sent this by message. The change in her behavior caught Liam's attention.
"Is there something else you need?" he asked.
After a brief pause, Lydia spoke again.
"I'm moving to a new place tomorrow. I've hired people for the heavy lifting, but I need someone to help with things inside the house."
This had nothing to do with football. Liam hesitated.
"If you help me, I can put in a good word for you with the coach about getting some playing time."
The offer was tempting. After thinking it over for a moment, Liam accepted.
"Be at the address I sent you at nine tomorrow morning."
After leaving the club that day, Liam returned home. As soon as he entered his small apartment, he called out again.
"What exactly does the Lust Fusion Device do?"
"The device strengthens the user through sexual interactions with others. The effects gained vary from person to person."
Liam felt a surge of excitement.
"How can I track my growth?"
"Simply think about your abilities."
A screen appeared in his mind.

...
In terms of football, he only had the short pass skill.
"What do I need to do to improve quickly?" he asked.
"Interacting with suitable individuals is sufficient."
He hadn't had anyone in his life for a long time.
With this system, everything could change.
That night, Liam fell asleep thinking about the beginning of his new life.
