Your P.O.V
You wake up with Sebastian's arms around you. You smile, and get up. You walk to the bathroom, and realize something, it's Erin's birthday today. You smile at the memory of her being born. Suddenly, arms wrap around your waist.
"Love, it's Erin's birthday today. What should we do? What does she want?" Sebastian's voice sounds worried, and you smile more. You turn to face him.
"Don't worry. She coming-" You cut off right as the door opens, and Erin comes in with a smile on her face. She walks into the bathroom to you and Sebastian, and stops. She smiles.
"Hey mom and dad, I have a question." Erin says in a small voice, letting us know she is serious.
"Go ahead." You say back in the same small serious voice.
"If it is okay with Ciel, do you think we could have a ball for my birthday..." Erin trails off, looking at us.
"I'm sure he'll be fine with it." Sebastian says, wrapping his arms around you. You smile, loving the way he does it out of no where.
"I don't mind." You answer. She smiles.
"Okay. Thank you." She walks out of the room, closing the door behind her. You look out the window, seeing Erin with a hooded figure. The figure takes down the hood, revealing a stunning good looking boy about Erin's age. You are by the window suddenly, keeping a sharp eye on the boy. Erin smiles at him kindly. You wonder who this could be, but before any other thought comes to your mind, Erin looks up to your window, so you make it look like you and Sebastian are talking. Erin turns back to the boy, waving at him as he leaves. You can see just how happy she is when she is with that boy, and you wonder even more.
"Sebastian, who do you think that is?" You ask him, grabbing for his hand. He tangles his fingers with yours.
"Probably someone she likes, love." He answers, and quickly adds, "Like how I love aboutt you." He kisses your forehead.
You smile. "You're right. We should make Erin's sixteenth birthday ball one she will never forget," You say. Sebastian smiles.
"So what you need to, love. You always do." You and Sebastian walk out of your room together, holding hands as you head to Master Ciel's study. You walk in to see Lady Elizabeth standing there. She smiles at you.
"Lord Ciel, you have probably already heard, but Erin would like a birthday ball," you tell him. Lord Ciel looks up at you.
"I am aware. She may have one. It's the least I could do," Lord Ciel smiles.
"Than it's decided. I'll throw the ball for her." Lady Elizabeth says. She looks at you with a smile.
You nod. "Thank you, Lady Elizabeth." You bow your head. Lady Elizabeth walks out of the room, dragging Sebastian with her. "Come. I need your help." She says. The door closes behind her. You are left with Lord Ciel.
"(Y/n), who is that boy Erin was with earlier?" Lord Ciel says. "He looked suspicious."
You nod your head in agreement. "I don't have any idea, my lord. This is the first I've seen him," you tell him.
"I want him kept after the ball. I want to know more about this person." Lord Ciel says. You bow your head.
"Yes, Lord Ciel." You say. "Thank you for doing this for her. She seemed really happy."
Lord Ciel nods. "You're welcome. Go and help plan. Elizabeth can get carried away." He dismisses you. You walk out, seeing Andi leaning against the wall, his arms folded and eyes closed.
"Andi? What's wrong?" You ask him. He looks at you.
"That boy. He bugs me." He tell you.
"Who is he?" You ask him.
Andi looks confused. "Erin didn't tell you?" He says. You shake your head no. "That's her lover. She's been seeing him for a few weeks now."
You are shocked by this. Her lover?
....timeskip to ball.......
The ball is fantastic. Everyone who is anyone is here. You watch as Erin dances with her lover. You still haven't told Sebastian. He walks up to you. "Sebastian, that boy Erin's dancing with is her lover. Andi told me earlier." You tell him.
"That's some news," he says. "What did master Ciel say?"
You fidget. "I haven't told him either." Sebastian looks at you like you're crazy. "He said he wanted to know after the ball, not before. So I didn't say anything." You tell him quickly.
Sebastian kisses your head softly. "I'll get her. We might as well know now." He says. He glides through the dancers, getting Erin and the boy. You smile as Erin, Sebastian, and the boy return. "Erin, who is this boy?" Sebastian asks.
Erin blushes. "Mom, dad, this is Max, he's my lover," Erin says, her face embarrassed. "I was going to tell you earlier, but I thought it would be best to wait," she says.
Max smiles. "Nice to meet you. Especially the two of you. Lord Ciel's body guards. An honor," Max says. You smile.
"We are mearly servants in the Phantomhive household. Nice to meet you, Max." You say. Sebastian looks the boy over, his eyes blank.
"If you hurt Erin, I'll end you." Sebastian says.
Max swallows nervously. You smile more. "Yes sir. It won't happen. I love your daughter. And Andi. He's a good brother." Max says.
Erin smiles. "Want to dance?" She asks Max, who nods. She and Max walk to the dance floor, their movements gentle.
You look at Sebastian, your face amused. "No worries, love. She'll be fine. I don't sense anything suspicious about the boy." You say.
Andi comes up then, his face looking bored. You touch his cheek. "I'm bored," he says.
You let your hand drop. "Have you danced with anyone yet?" You ask.
Andi shakes his head no.
You look over the crowd, seeing a lonely looking girl with a book in her hands across the room. You smile. "Go ask her to dance. Be a gentleman." You say.
"Well, it's something to do," Andi says and walks to the girl, who blushes when she sees Andi. Andi extends his hand to the girl, who takes it with a shaking hand. Andi and the girl dance for three songs, and their faces are covered in smiles. Sebastian moves in front of you, holding his own hand out. You take it. You two dance swiftly through the other dancers, who look at you both with smiles.
Once the ball is over, Andi and the girl walk in from the balcony, and the girls face is beat red. You smile. "We're going to be a happy family, Sebastian. I love you." You say.
Sebastian smiles. "I love you more, (Y/N)." He says.
As time went on, Andi and the girl, Sarah, got married and had triplets together. Their names Andi Jr, Frederick, and Marissa. Erin and Max had two children. Their names Maxine and Eric. You and Sebastian have been very busy with helping out with the kids, Lord Ciel, Lady Elizabeth, and the cases and chores, but you and Sebastian get through it together. And the two of you lived in happiness with your families.
