The soft sound of footsteps is heard in an abandoned playground.  Y/n stood feeble in front of the entrance, looking at the surrounding area with a look of longing.  She still remembers the days when she was young. Her parents would always take her to this playground over the weekend, doing some activities together. Either running and chasing after each other, having a small picnic with the three of them or playing on the swing with her dad pushing her from behind while her mother was in front.

'How nostalgic!'

This place is everything to her. It's extraordinary that this playground is rarely visited by the locals. The scenery is lovely and wonderful. The flowers there are in bloom and the green of the tree indeed shows its freshness. How can this kind of background aren't catching their attention?

Well, it may be because it is quite far from the residential area but for Y/n and her family, they absolutely fall in love with the place because they feel that the park is designed just for them as if it were their paradise. Only theirs. And because of that, if Y/n had any problems with her life, she would come to this park to clear off her mind. No one will disturb her peace there. She could do what she always did, settling on the swing while relishing the soft breeze.

That's what she thought until a voice hit her ears from behind, startling her. She whirled her head only to make eye contact with a pair of purple eyes. 'Eek!!'  Then, she gets up and jogs away from the swing. When she looked back, the girl she had seen was gone.

"What the- Where has the girl gone?"  Y/n screamed. Her heart thumping rapidly. At the time, she didn't mind if people think she's crazy for yelling so suddenly. All she had in mind right now was how can there be anyone else in the park beside her. It's been a long time since the park has been visited and for someone to suddenly appear there...

"God.. This is creepy", she murmured.

"Hey! I'm not creepy."

When she heard the voice, she quickly spins her body and right there, stood a teenage girl. Her long purple hair moves slightly as the wind blows and her purple eyes were on her, face looking angry. Probably because of Y/n's words just now.

'It just a teenager..'

The shocking incident really made her body goes tense and as soon as she realized it was just a teenage, her body began to calm down. She peeked over at the girl with a curious look. There are so many questions that she'd like to ask her.

"What is your name if I may ask you?", asked Y/n, extending her right hand out.

The girl looked at her with caution, wondering if she should greet or let the handout. Y/n can't blame the girl because her actions are completely logical. An unknown adult asks you what's your name all of a sudden. Who doesn't feel wary about that?

"My name is L/n Y/n. You don't have to feel afraid. I'm not going to do anything to you, I'm harmless. You can really trust me."

The girl looked at her hand again before she greeted her with a small sigh. "Hanae Shiratori. Nice to meet you, ma'am."

Y/n is shocked when she heard the girl's voice carefully. She might don't realize it earlier because she's too frightened of the small incident just a moment ago. But on further inspection, she found out the girl's voice wasn't too high of the tone. It sounds a little bit deep, low and very mature. Like an adult woman. Though, her own voice didn't like one.

"Um, Hanae isn't it? Can I ask how can you be here in this playground? And then, how long have you been to this place?"

The question that came out of nowhere surprise Hanae a little, making her body twitching in shock. She raised one of her eyebrows, giving the adult woman an odd look. "Why do you even want to know about that?"

"It's because-"

"Well.. Well.. Well.. What do we get here?"

Another voice struck her from behind. Y/n feels ultimately fed up. What's up with everyone who's sneaking her from behind today? Is it fun to see her jump out of shock like a crazy cuckoo?

"Hanae, who is this woman?" The purple-haired man with a pair of gold eyes asked Hanae, his right hand around the girl's neck.

'All right! Who is this weird guy? It looks like he's close to Hanae. Her family members, perhaps?'

"I don't know. I see her sitting on that swing and it kinda seems that I have surprised her just as you did just now," Hanae explains.

"Oh, I see." The stranger nodded his head as if to understand the situation at that time. Although Y/n pretty much sure thinks that there is nothing to understand frankly. Then, he turned his face towards her, settling on a big smile on his lips. "Hi! My name is Shiratori Naoto. Thanks for taking care of my sister for a while."

"Wait! I'm not taking care of her.." Y/n waved her hands nervously.

"Ah, no. If it wasn't for you talking to her, she would have run away somewhere else. We're playing tag, actually"

"Tag?"

"Yup! Both of us will try to tag each other silently. For example, I see Hanae hiding behind one of the bushes over there. So, I'll sneak in slowly and tag her from behind by tapping on her back"

"That means I have lost and the loser has to answer all the other player's questions," Hanae continued.

"Oh, it's a bit different from the original tag game.." Y/n scratch her head awkwardly. The games she often played in her childhood, why they are so different. Is it updated? Or maybe she's really getting old and the world become better, including games like this?

"Of course. That's because of the tag game we both know. It's more challenging this way than the old ones."  Naoto said cheerfully. Y/n could see the excitement in his golden eyes as if there were stars shining brightly in it. She then turns her attention to Hanae. Unlike Naoto, Hanae has a proud look on her face, feeling impressive of the design of the tag game in their own way.

'She looks like she's enjoying her fun there' Y/n thought as a smile begin to carve on her face.

"Hanae! Naoto! Sigh.. I'm tired of looking for you both. I was wondering where you two went since you left me alone at the supermarket."

A woman in a white shirt and black blazer ran towards the three of them. Her dark purple hair stuck to her sweaty face as she ran everywhere, looking for her two siblings like one who had lost their child.

"Naomi-nee!" The two sibling exclaims.

Upon arriving at the scene where they were standing, the woman bent over her body, her hands down on her knees. She huffs heavily, trying to regain her breath. Y/n feels sorry to see her condition. She put her hands behind her back, asking her to take a seat in one of the swing and without any words coming out of her mouth, the woman gave her a small nod.

It took a while to wait for her breathing to return back to normal but Y/n had time. She didn't feel like going home early today. Either way, she wanted to spend a little more time at the place and maybe, get to know the three weird siblings more deeply.

"You kids.." The woman is face-palming as she said that. Her face looks disappointed. She looked at both of her siblings, shaking her head slightly. "Why did you two run from the supermarket? Plus, leaving me alone there"

Hanae and Naoto could only bow their heads down. No sound coming out of them both. 'They must have felt very sorry for their actions' Y/n thinks as she just looks at the scene that was happening before her eyes.

"Sigh! I'm so sorry.. Did they disturb you?" The woman asks towards Y/n, her eyebrows furrowed. She looks absolutely troubled.

"Eh! N-No, they aren't. We're just having some talk about their game."

"Really?"

Y/n nod. "It's interesting to hear their own way of tag game."

"Oh!" The woman chuckles, smiling brightly at her. "I agree with you. Their idea is to make the game more challenging, how clever! I can't even think of such an idea."

"Yes!"

"Anyway, my name is Shiratori Naomi. I'm their oldest sister. Thank you for spending your precious time on these two troublesome kids."

"Hehe... You're welcome. I'm L/n Y/n. Nice to meet you!"
