The Relationship Begins- Kagamine Len X Reader AU?

A/N: This is a sequel to my first Len Kagamine X Reader. However, this story is understandable without reading my first installment.

“Y/N?” A voice called.
You stirred a bit. It felt like you’d just fallen asleep. Now you were waking up again? Who was waking you up? Was it morning already?
You couldn’t see well in the dark room, but from the little you saw you knew that you were face to face with Len Kagamine. Your cheeks turned red. You remembered the previous turn of events involving him. However after the kiss, he simply left the room. You were left with Miku and Rin laughing at you as you wished to go home so badly.
Now the blonde was facing you again. You got a glimpse of a clock. It was 3:00 at night, and Miku and Rin were sleeping. The boy was squatting down with his knees sticking out. Len had carefully snuck into the room and woke you up without disturbing Rin or Miku. But why?
“Len?” you whispered as a response. “Why’d you wake me up?”
“Can we talk?” he asked, standing up. “I mean, in my room?”
You were confused. He just left you alone with your friends, and now wanted to talk again? Maybe he wanted to talk without them.
Despite these thoughts, you carefully scooted out of your sleeping bag and crawled a bit across the floor. You slowly stood up.
“It’s a yes?” he asked quietly.
You nodded. “Your room’s down the hall, right?”
“Mm-hmm,” he muttered then began to leave his sister’s bedroom. You followed him down the hall and into a room. He opened the door, as if telling you to go inside first. After you walked in, he quietly shut the door.
This was the first time you got a real glimpse of Len’s room. Even in the dark, you could see he had a twin-sized bed in the corner of the room with a yellow comforter. The walls were painted red with posters with funny sayings on them. Unlike the TV Rin owned, Len had a desk with a laptop on it. There was various pieces of paper tossed on his floor.
“Feel free to sit down,” he said a little louder than he spoke in Rin’s room. You sat down on the side of his bed and he sat next to you.
“So, why am I in your room?” you asked, at a moderate volume.
Len nonchalantly sat down next to you. “To talk,” he replied with almost no emotion.
“About what?” you questioned impatiently.
“About what happened today. You like me, (Y/N).”
You blushed again. “Len. . .” you mumbled.
“Do you know why I asked you that?” he turned to face you. You saw something in his eyes. Was it, worry?
“Do you like me, Len?” It was all coming together now. He wanted to ask you out! Your heart was pounding.
“Don’t say it that loud.” The normally calm boy was blushing like mad. “I-I. . .”
You cut him off. “Did you invite me here to ask me out?”
“I did.”
You nearly squealed. You’d always imagined what it would be like with Len as your boyfriend. Now he was actually asking you out!
“Of course,” you blurted out. It was very hard for you to keep your voice down.

*Time skips XD*

“WAKE UP!”
You felt the air completely knocked out of your lungs. There was something huge on your back.
Miku gasped. She felt it as well.
Rin Kagamine had belly-flopped onto the two of you to wake you up.
You tried to get up and knock her off of you. “What the heck, Rin?!” you exclaimed. Rin just laughed.
“Just why, Rin?” Miku asked, almost as if she had given up on life.
“Because you guys have to be home by two and there’s so much we need to do!” Rin spewed out in a childish manner.
“But you didn’t need to jump on us!” you scolded.
“Just get up! My mom bought doughnuts for breakfast and you have to hurry if you want any!” Rin got up and ran for the door.
“Don’t just run away from me!” you screamed as you chased after Rin.
“Catch me if you can, (Y/N)-chan!” Rin stuck out her tongue and raced down the stairway.
You heard Miku getting up, joining the chase. By the time you and Miku had reached the bottom of the stairs, Rin was in the kitchen beside a laughing Mrs. Kagamine.
“Wow Rin, you sure got them out of bed quick.” Mrs. Kagamine snorted. She was reaching into the refrigerator to get drinks. “What would you like to drink?”
“Milk,” Miku and yourself replied at the same time.
“Orange juice!” Rin yelled, sitting down at the table.
“Not so fast, Rin.” interrupted Len, who was already at the table. “According to (Y/N)’s dare, you can’t have oranges. Rin will have water.”
You laughed and sat down opposite of Rin and next to Len. "That's right! No oranges with your doughnut either."
You, Len, and Miku began to laugh. You laughed until Mrs. Kagamine asked you four what flavor of doughnut you wanted. Len asked for banana, Miku and Rin asked for chocolate, and you asked for a glazed one. The doughnuts were passed out and the four of you began to eat, preparing for what Rin had in store for the following day. . .
