The park was filled with the joyous sounds of children laughing and playing. Minjun was busy playing with his friends, their imaginations soaring high. Haechan, Renjun, and Iseul sat together, watching the little ninjas and heroes in action from a cozy corner.

Iseul couldn't help but smile at the sight of Minjun, fully immersed in the role of Naruto, displaying his determination and passion just like the beloved anime character. She discreetly captured these precious moments, knowing they would become cherished memories for Minjun and his friends.

"So, your name is Iseul," Renjun said, breaking the silence with a warm smile. "It's nice to finally know the name of the stranger with whom Haechan's bag got swapped that day."

Iseul blushed, recalling the serendipitous encounter that brought them together. "Yes, it's Iseul," she replied, offering a shy smile. "And it's equally nice to know your names too."

Haechan rolled his eyes playfully. "Yeah, yeah, laugh it up," he said, nudging Renjun. "I already told you, I got caught up in the excitement of the moment. But at least I didn't forget Minjun's birthday!"

Renjun chuckled, teasingly patting Haechan's back. "Well, you did make it up to him with this amazing surprise. I must say, this anime-themed party is top-notch!"

Iseul nodded, her eyes sparkling with admiration. "It's fantastic! You really went all out, Haechan."

Haechan grinned, a hint of pride evident in his eyes. "I wanted to make it special for Minjun," he said, watching as Minjun's laughter echoed through the air. "He's such a considerate and caring kid. He never asks for much, and I wanted to give him something he'd love."

Iseul's heart warmed at Haechan's words. "You've done a wonderful job. It's clear how much he loves you and how much you care for him."

Renjun chimed in, "It's true. Minjun may be young, but he's perceptive. He knows the value of love and care, and you give him plenty of both."

Haechan's cheeks flushed at the praise, but he was grateful for their understanding. "Thanks, you guys. But I couldn't have done it without your help, Renjun. You've been my partner in crime throughout this planning process."

Renjun chuckled. "Of course, I had to ensure that the little guy had a birthday to remember."

Just then Minjun rushed towards them with a beaming smile, his eyes sparkling with excitement. "Hey, Hyungdeul! Noona!" he called out, inviting them to join the ongoing games. Laughter and cheers surrounded them as they happily accepted Minjun's invitation, blending into the vibrant celebration.

The day after Minjun's birthday felt like any other cozy afternoon at the cafe. Haechan and Renjun, engaged in their usual work routine, were joined by Minjun after school. The scent of freshly brewed coffee enveloped them as they found themselves immersed in the comforting ambiance of the cafe. Amidst the gentle hum of conversation, they not only enjoyed each other's company but also added a productive touch to their day, seamlessly blending work and companionship.

Minjun, with his school bag at his feet, was engrossed in his homework, occasionally glancing up to exchange a smile or a nod with Haechan and Renjun.

Haechan playfully teased Renjun about his gaming skills, and Renjun retaliated with a witty comeback, leading to a friendly banter that had them both laughing. "You're just jealous because I beat you in that racing game last week," Renjun said, grinning mischievously.

Haechan raised an eyebrow, pretending to be offended. "Oh, please! It was just a fluke. You got lucky, that's all."

"Sure, keep telling yourself that," Renjun teased, playfully nudging Haechan's shoulder.

Minjun looked up from his homework, amused by the ongoing banter between the two. "Hyungs, you're both good at games," he said diplomatically, not wanting to take sides.

Haechan and Renjun exchanged a knowing look, then burst into laughter again, realizing how competitive they could get over the silliest things.

As evening approached, the cafe began to empty out, and the atmosphere became more relaxed. The trio continued their work, occasionally pausing to chat and share funny anecdotes from the day.

The familiar jingle of the cafe's doorbell announced the arrival of a visitor. Iseul walked in, a warm smile on her face as she greeted Haechan, Renjun, and Minjun.

"Hey, guys! Mind if I join you?" she asked, her eyes twinkling with happiness.

"Of course, not!" Haechan replied. "You're always welcome here."

She made her way to the table where Minjun was sitting, taking a seat beside him. Leaning in, she gave him a friendly smile and asked, "Hey, little ninja, what's up? Done with your homework?"

Minjun nodded, a proud smile on his face. "Yeah, almost finished. It wasn't too hard today."

Iseul chuckled, impressed by Minjun's diligence. "Great job! If you need any help, just let me know, okay?"

Minjun smiled and Iseul reached into her bag, pulling out a beautifully wrapped present. "Minjun, this is for you," she said, handing him the gift.

Minjun's eyes widened with surprise and delight. "For me? Thank you, Noona!" he exclaimed, carefully tearing open the wrapping paper to reveal a set of colorful markers and a sketchbook, perfect for his drawings and doodles.

Iseul chuckled warmly. "Well, Minjun, I didn't bring a present on your birthday, so here I am compensating. I wasn't sure what you'd like, but these markers and a sketchbook are just a start. If there's anything else you want, just let me know!"

Minjun's eyes lit up with gratitude. "No, Noona, this is perfect! I love drawing, and these markers are awesome. Thank you so much!" he exclaimed, a genuine smile lighting up his face.

"I'm glad to hear that," Iseul replied, touched by Minjun's sweet words.

As they continued chatting, Haechan came with a caramel latte in hand, placing it before Iseul. Her eyes widened in surprise, and she couldn't help but ask, "You remembered my favorite drink?"

Haechan smirked playfully, "Of course, I have an impeccable memory."

Renjun chimed in, teasingly adding, "Yeah, he can remember everyone's orders. Quite the multitasker, our Haechan."

Haechan shot Renjun a mock glare, playfully rolling his eyes. "Well, someone has to keep this place running smoothly."

Iseul couldn't help but giggle at their banter, admiring the camaraderie between the two friends. "Well, other than being a great vocalist and poet, you’re an excellent barista too," she said, giving Haechan a sincere smile

Haechan shrugged modestly, trying to hide his slight embarrassment. "It's just a hobby," he mumbled.

"Oh, I almost forgot," Iseul said with a smile, reaching into her bag. "
