It was Saturday morning and Jimin was preparing a breakfast for his son and himself.

"Daddy!" Jiseul cried out as he rush his steps to his father.

Jimin halt his cooking and close the stove so that his cooking doesn't burn. He crouch to his little one.

"Where's mommy? I can't find her anywhere." He pouted. Jimin sigh at it before stroke his son's hair.

"She went out."

"Where? Is she coming back?"

Knowing that question were a bit hard to answer the little one makes him sad. 'Your mother won't be back, Jiseul. I'm sorry.' He thought to himself.

"Daddy?" He was snap out when the little one call him. He smile at him.

"Um... she'll be back." He simply said, convincing the little one much.

Jiseul's face lit up when he heard that his 'mother' will be back. She's not leaving him anymore. Well, that's what he thought.

"Now, sit here. The breakfast is almost ready." Jimin said as he lift the little one and sit him at the dining table before he went to the kitchen and continue what he left.

Jiseul eyed on Jimin's phone that were place on the table. He smile as he took the phone and search for Nara's contact before pressing the call button.

["H-Hello."]

Nara were still asleep that time since it was Saturday. Plus, she's not a morning person. Never a morning person.

She was a bit annoyed that someone just had to disturb her sleep. Her eyes weren't fully opened when she answer the call.

"Mommy!"

Just then, her eyes widened when she heard Jiseul's voice. She quickly sit upright.

["O-Oh... yes.. Jiseul-ah. Why did you call?"]

"Where are you? Daddy is preparing a breakfast for us. Come back fast!"

As for Jimin, his eyes widened when he saw Jiseul were calling Nara early in the morning. He rush toward him and place two plates on the table.

The little one hand the phone to him as he nervously take it. "H-Hello." He stuttered.

Nara was a bit relief to hear Jimin's voice so she went back laying on her bed, eyes closing.

["Oh, hi."]

She muttered in a sleepy voice. Jimin smile at that, thinking that it was cute to hear her sleepy voice.

"I'm sorry about Jiseul." He said as he walked away from his son and took a glance at him every now and then.

["No, it's okay."]

"Daddy! Tell mommy to come back fast! I'm hungry!" Jiseul exclaimed in the background. Nara heard that and she was suddenly wide awake.

"Um, I'm sorry about th—"

["I'm up! Just wait. Bye."]

She hung up the call and immediately strode in the bathroom to clean herself. It was still early and now she had to rush here and there. Plus, it's a freaking Saturday.

'Oh my God, I don't even know why am I doing this. I'm not even his mother!' She whined to herself and wear her casual outfit. As usual, a student style. Wearing a sweatpants and a black tee with her hair tied up in a messy bun.

She grab her phone and left her room. Rushing her steps to the main door as she ignored her family's stare.

"Dad, I'm using your car!" She exclaimed as she took the car keys and hastily went in the car.

"Is that really your sister?" Their mother blinked her eyes for a few times in disbelief.

She know her daughter. She's a lazy person. To see Nara woke up in the morning was something very very rare.

"I... have no idea... on who's that." Jungkook muttered as he stared at the main door blankly.

'What supernatural shit had possessed her?' He thought.

Nara rang the bell a few times and pant a little bit because she was rushing so hard to get there.

The door creak open, revealing an excited little boy smiling at her.

"Mommy!" He jumped.

Nara caught him in her arms and close the door behind.

"Good morning." She muttered when she saw Jimin preparing the breakfast. He smile at her and reply, "Good morning too."

Nara took a seat at the dining table as if it was her own house, being so comfortable with everything. Jiseul's impact. If not because of him, she might have not come here and just stay alone with Jimin.

'That's a big no, fam!' She thought to herself.

Nara eyed on the breakfast, swallowing hard as her stomach growl in hunger. Jiseul heard that as he giggled at her.

"Daddy, faster! Mommy is hungry." He whined. Nara giggled at that as she watched Jimin coming back and forth from the kitchen for the food.

After awhile, finally he sit across Nara. Jiseul were sitting on her lap which is a bit uncomfortable for her as a gluttonous person.

"Jiseul, come and sit here. You're disturbing mommy." Jimin said.

Nara blushed a little when he called her 'mommy' which was so damn unusual. But she cover it up.

Jiseul whined at his father as he bounced on Nara's lap in protest. "I want mommy to feed me! It's been a long time." He whined.

Jimin look at Nara for assurance and at the same time mouthed a 'sorry' but she doesn't seem to be bothered about it and smiled.

"It's okay. So, Jiseul, what do you want to eat?" She asked, eyeing the foods on the table.

"The toast! And scrambled egg." He cheered.

Nara reached out the toast with Jimin's help and place it on his plate before spreading the scrambled egg on top of it.

"Here." She said as she fold the toast and feed Jiseul as if she'd done it for a long time.

"Uh oh." She muttered as she wiped Jiseul's lips that the little piece of egg stuck at the corner. She lick her thumb and giggled at it.

Jimin was a bit stunned when Nara did that as if Jiseul is her real son. Like Jiseul is their actual son instead of with his late wife.

He is glad that Nara get along with his son well. Although they were still a stranger to each other.

After breakfast, Nara planned to sneak out of the house without Jiseul find out. She need to get her assignment done before the due date.

"I'm sorry that I had to burden you."

"Don't ever mention about that. I'm fine." She muttered as Jimin helped her to sneak out.

"Mommy!" Their eyes widened when they heard Jiseul's voice behind them. "What are you doing?" He continue.

"Nothing. We're just... talking." Nara convince.

"Can we go out today?"

"No!" Both of them said in unison. Jiseul look at his 'half parents'.

"I mean, mommy have to work. Perhaps... tomorrow?" Nara suggest. Jiseul smile at her and nod.

"Promise?" He let out a pinky swear. Nara crouch down on him and intertwined their pinky fingers. "Promise." She reply.

"Now, I have to go. I'll see you tomorrow."

"Huh? You won't come back tonight? You've promised me that you will accompany me to sleep." Jiseul state in a disappointing tone.

"Jiseul, you have to under—"

"It's okay." Nara muttered as she look at Jimin. Even though she know Jimin wouldn't let her strain herself to drive back and forth from her house to Jimin's, especially at the middle of night, but this is the least that she can do. She still have no idea why she do all this, but something about Jiseul changed her life.

"I'll try to be back early so you can sleep early, hm?" She said. Jiseul smile at her and peck her cheek lightly. "I'll wait for you."

"Now go in. It's cold out here." Nara advised. Jiseul nod his head and run inside as he close the door.

Nara stood up. "You know you don't have to do that." She heard Jimin said. Nara look at him and sigh, "You still didn't tell me why Jiseul called me his mommy." She stated.

"Is that why you stayed?" Jimin made an assumption, resulting Nara to shook her head.

"I don't know," she paused as she stare at the main door. "There's just something about Jiseul that made me do all the things I don't." she continues.

Jimin smiled secretly when he heard that. It somehow made his heart fluttered but he doesn't know the reason.

"It's because," He started. Nara turn to look at him in curious. "You look like my late wife." he sighed, averting his gaze away from her.

"Oh." was the only thing she said after that. 'That was one major reason, huh.' She thought.

"Um, I think shall go now." She said as she unlocked the door. "You're a strong single father, Jimin. I'm proud of you." she said before she hopped in the car and drive away.

A small reassuring smile tug at the corner of his lips when Nara said that. More like complimenting him.
