Chapter 123

Previously on Chapter 122

"I love you too, Senku" she said. I lean down, finally closing the distance between our lips as I capture her lips with mine in a tender kiss. She kisses me back almost instantly. I pull her closer by the waist as I tilt my head, deepening the kiss. Y/N is a strong fighter with a beautiful talent. I'm proud and grateful that I'm the one who gets to call her mine. She's everything to me.

-Cocktails and Fun-Time-

I let out a nervous laugh the moment we walks out. First it was poker. Now, we have a whole casino. Francois is serving the bar with alcohol. She's even being thoughtful to create mocktail for Suika so she won't feel left out.

"What about you, Y/N-Sama? What would you like to drink?" She asked. I blink my eyes as I stare at her. My arms is carrying baby Byakuya. I smile softly at her and lightly shake my head.

"No need... I can't risk drinking, since I need to give Byakuya his milk. It could potentially be harmful for him" I said. She hums softly and nods her head. She turns around and walks off, serving everyone else on board.

"Ma... mama..." Byakuya cooed. I turn my head to look at him and smiles softly. I playfully rub my nose against his. He let out a giggle and claps his hands. "Mama!" He said, kissing my cheek which makes me smile.

I flinch when I feel a pair of arms snaking around my waist. I turn my head to see Senku. He let out a chuckle as he realize he had startled me. "Sorry, love... didn't mean to scare you..." he said, hugging me closer. His chest is pressing against my back.

Byakuya let out a protest and starts pushing at his face. "Ngggg... my mama!" He protested. Senku grunted as he still tries to hold me. "Mama!! My mama!!" He cried out. But Senku didn't let me go as they have a playful glaring battle. In the end, Byakuya end up biting Senku's cheek. I let out a laugh as Senku finally recoils from holding me as he rubs his sore cheek.

"Byakuya, honey... be nice to your papa, okay?" I said. Byakuya only pouted as he buries his face into my shoulder. I let out a soft giggle as I gently caress his head. "Awe... it's okay, baby. Mama is not angry, okay? Mama just wants you to be nice to papa..." I said.

"Mm..." he hummed. He pulls away from me and lift his hands to Senku. "Papa... up..." he said, wanting Senku to hold him. He makes grabby hands at Senku. Senku stops rubbing his cheek and pick him up.

"You're one feisty boy, aren't you?" He said, chuckling softly while holding our son. Byakuya only clap his hands on Senku's cheeks. Senku flinching on every clap, making me giggle softly at the father and son bonding. "Don't... laugh... and... help... me!" He said with every flinched.

"Byakuya... don't hit your father, baby" I said. He turn to look at me. He turns to look at Senku again and place a soft kiss on the tip of his nose. "Better" I said, walking up to them. I place a soft kiss on Senku's cheeks and one on Byakuya's head.

"Y/N!! Music please!!" Someone said. I turn my head to see it's Nikki. I smile softly at him and walk towards the piano. I take a seat and starts to play a piece.

Everyone gathers around us as they enjoy the piece that I'm playing. Byakuya claps his hand softly as he watches me with eyes full of wonder. Senku gently adjust him a little higher. "That's your mama~" Senku said.

Byakuya tilt his head up to look at him, then turn back to look at me. He let out a gleeful laugh and clap his hands excitedly. "Mama! Mama!" He chanted. It makes me feel like I have a mini fan. I let out a soft giggle and shakes my head as I continue to play.

The piece eventually ended. I hear a loud cheer and turn my head to see it's coming from Nikki. "I'm your biggest fan, Y/N!!" She cheered. I let out a laugh at what she just said. I lightly shake my head as I turn to look at Byakuya who also claps while laughing, as if saying he's the real number #1 fan of me.

"Okay. Alright... I admit defeat. Ain't no way I can win against the son of the artist..." Nikki said, giggling softly which makes everyone on board laugh along with her statement. Byakuya giggle and claps his hand, making everyone coo at his cuteness. Senku smiles at his son and place a loving kiss on his cheek, making him squeal and laugh even more.

Byakuya yawn a little and snuggle closer into Senku's embrace. He closes his eyes and drift off to sleep. Senku stares at him with a soft gaze. I smile softly as I walk up to them. Senku gently hands Byakuya to me. I tenderly cradle him in my arms.

"We should probably get some rest, Y/N..." Senku said. I turn to look at him and nod my head. "Okay, Y/N and I will be heading to our room" Senku called out to the others. Everyone agrees and wish us goodnight. Senku place a gentle hand on my lower back. We make our way inside and into our room. I gently lay Byakuya inside the crib. I lean down and kisses his head.

"Now that the little mischief has fallen asleep, now it's time for the papa to get some attention as well" Senku said. I yelped in surprise when he throws me over his shoulder. I cover my mouth as I turn to look at Byakuya, worried that my voice would wake him.

"Senku!" I whisper-yelled scoldingly. He let out a laugh and walks up to the bed. He gently lays me down before climbing in next to me. He pulls me closer to his side.

"Finally... I've been craving your warmth for the entire day" he muttered as he hugs me. He scoots down to place his head on my chest, being the small spoon. I let out a giggle as I run my hand through his hair. "Hmm... that feels nice" he said. He pulls away to look at me and smiles. He leans up, pecking my lips. "I love you, Y/N" he said.

"I love you too, Senku..." I said. I place a soft a kiss on his forehead. He smiles contently and place his head on my chest once more. He closes his eyes. Soon, the sound of his breathing evened out, letting me know that he has fallen asleep. I smile softly as I hug him closer. I close my eyes and drift off to sleep.
