You woke up to a pair of red eyes staring at you.
"Gilbert!" you screamed, sitting bolt up right and smacking your forehead into Prussia's. "What the heck?! How did you get in here?!"
Rubbing his bruised forehead, Prussia looked reproachfully at you.
"Calm down, frau," he said. "I just vanted to vake you up, zhat's all."
You groaned and flopped back onto the pillows.
"Why did you need to wake me up at -" you glanced at your alarm clock "-five in the morning?! Gilbert, I was sleeping!"
"Ja, lieb, I know, but I have somezhing important to tell you."
"Gilbert," you groaned. "You just want to say something? Look, at five in the morning, I couldn't care less if my house was on fire!"
"Vhat about if I loved you?" he asked, watching your face closely.
"What?" you said, head snapping up.
"Nozhing," he smirked, sliding off your bed and heading towards the door.
"Gilbert Beilschmidt, get back here now!" you demanded. "What did you say?"
He turned back to look at you and smirked again.
"You knov vhat I said, kesesese," he grinned, crossing the room to sit back down on the bed.
"Gilbert?"
"Ja?"
"I love you too," you whispered, blushing fiercely.
