This scenario is a request from @YowattupBITCH101010. Enjoy! (I love the username btw)

Tanjiro Kamado:

You let out a heavy sigh, plopping down on your bed. Long days of training never fail to drain your energy.  Subconsciously, you begin singing. It's a lullaby your mother used to sing to you as a child. The love-filled words bring you a sense of peace; there was nothing like it. 

A loud bang drives your attention away from the song. You immediately get up from your bed and look around. What you see surprises you: your boyfriend, Tanjiro, is on the floor of your bedroom. The door you remember closing hangs wide open.

"T-Tanjiro!" you shriek, nervous he may have heard you, "What are you doing?"

He sits upright, running a hand through his reddish-brown hair. A familiar smile spreads across his handsome face, putting butterflies in your stomach. 

"Sorry!" he shoots up and bows aggressively, "I heard your singing from the hallway. I got closer and leaned against the door, but it swung open. I'm sorry!"

You chuckle, "It's okay."

Grinning warmly, he walks over to you and sits on the bed. He motions for you to sit next to him, and you do. 

"If you don't mind me asking, what were you singing?" he wraps his arms around your waist and pulls you close to him, "It sounded beautiful."

A blush spreads across your cheeks, "T-Thank you. It's a lullaby my mom used to sing to me."

"Can I hear it?"

Nezuko Kamado:

The cool night air brushes against your skin, causing chills to spread across your body. You take a quick look around to confirm you're alone. 

"It's so peaceful out," you whisper to yourself, looking at the sky. 

The small forest by your house is something you'll never complain about; it calms you. Starting to walk around, you begin humming to yourself. You don't know what you're singing, but it had a bittersweet tune. 

After a while, you started to feel the presence of someone else. Usually, you'd become overly cautious, but something inside told you it's alright. You keep humming despite the feeling that someone is watching you. 

Looking over to the right, you see a familiar kimono, "Nezuko?"

A distressed squeak confirms your suspicions. The small girl walks out from behind a tree, coming towards you. She grabs onto your shirt and tugs it lightly.

"What is it?" you let out a small chuckle. 

"Can you sing again?" she looks up at you, meeting your gaze, "I like it."

A smile forms on your lips, "I'd love to."

Zenitsu Agatsuma:

You sit on the floor of the bathroom, waiting for the shower to warm up. It takes longer than you'd like; patience isn't exactly a skill of yours. 

"Warm up already," you whine, leaning over the edge of the bathtub. 

Accepting the shower's temperature, you take off your towel and get in. The warm water washes all your troubles away, letting you relax for the day. You start to sing a song your boyfriend taught you a few months ago. 

"You are my sunshine," you start, washing your body as you sing, "my only sunshine."

A more resonant voice continues the following line, "You make me happy when skies are grey."
