Living in Tokyo, all I want to do is laze around.

"So, Kai-kun, you'd better cherish Hanabi... or she'll slip away if you're not careful."

"Don't say that. I'm really afraid that you'll slip away, Hanabi... When I see your face, I feel like you'll disappear from my sight as soon as the car lights flash."

"Fireworks are nowhere near as mystical as Kai-kun makes them out to be!"

"It's true... You're like a dandelion; if you're not careful, you disappear into the blue sky without a trace."

"So, Kai-kun, what do you think Kai-kun is in Hanabi's eyes?"

"What is it?"

"secret..."

"Are you still keeping me in suspense?"

"Kai-kun, Hanabi understands. Even between lovers, there must be some things to keep secret, otherwise, after too long, you'll lose interest in each other... Of course, this doesn't refer to Hanabi, it refers to Kai-kun. So, Hanabi must keep secrets."

"Nonsense."

"That's not a fallacy!"

"I don't care, it's just twisted logic. Hanabi is so good to me... why should I think about anything else?"

Hanabi Hanamaru suddenly released her intertwined hands, reached out to hug his face, and looked down at him with her violet eyes, saying:

"Kai-kun... Hanabi is a very easily satisfied person. In fact, Hanabi is content as long as she can see Kai-kun happy. I have thought before that if Kai-kun finds another girl, Hanabi will watch him silently in the dark, without disturbing him or letting him see her."

Why don't you want me to see you?

"Because although Hanabi feels satisfied... she is still unhappy and disappointed... Hanabi is afraid that Kai-kun will not be able to help but care about her... At that time, Hanabi really couldn't bear Kai-kun's care... The thought that he still liked other girls made Hanabi feel satisfied... but she really couldn't bear it."

When Hanabi Hanamaru said these words, her expression was so moving that it was heartbreaking.

The two had actually shared many heartfelt words with each other during these few days, but each time, he still couldn't help but be moved by her.

Kai Uesugi smiled and half-lifted her up, letting her little arms wrap around his neck, then looked into her eyes and pressed his forehead against hers.

"Did you feel it?"

"What do you feel?"

"The love that's welling up in your husband's head."

"......No..."

"Hmm? Shouldn't Hanabi be saying, 'Yes, I felt it' at this moment?"

"But... Hanabi really doesn't feel anything, except that Kai-kun's forehead is a little hot. Could he have a fever?"

"Hanabi-chan, you should cooperate with me a little. After all, I'm a bit of an artsy person. Maybe if I'm in a good mood, I can even write you a poem."

"What's so romantic about writing poetry... Fireworks have very simple requirements, just want to buy more fireworks."

"What? I'm with you almost every day."

That's still not enough!

"Then what do we do? Do we have to maintain negative distance links all day long?"

"Oh no... Kai-kun has steered the conversation off-topic again!"

"Hahaha."

......

"Little Firework, why don't you sing me a song? It's been so long since I've heard you sing."

"What would you like to hear, Kai-kun? Merry Christmas?"

"No, just a simple birthday song."

"But when we get home later, everyone will sing for Kai-kun together."

"What I was thinking was that Hanabi-chan would sing it just for me... because I kept having this image in my head:"

"A girl carefully prepared a birthday cake for the person she liked at home, put up a banner, blew up balloons, wore a birthday crown, smiled, clapped her hands, and sang 'Happy birthday to you, happy birthday to you' to the person she liked in front of her."

At this point, Uesugi Kai forced a smile and said to the girl's cute face,

"That night should have been like this... I should have been enjoying Hanabi-chan's happy blessings... Amidst her cheerful applause, I blew out the candles, then looked up at her and smiled, saying, 'Happy 19th birthday, Kai-kun!'"

"

Hanamaru Hanabi smiled:

"Didn't Kai-kun say he didn't like celebrating his birthday? Now it sounds like he's very happy and looking forward to it."

"Idiot, what's important isn't my birthday at all... it's my daily life with Hanabi-chan, the happiness I feel seeing her wish me a happy birthday... If I were alone... it wouldn't matter whether I celebrated it or not."

"So, Kai-kun's actions were largely inspired by Hanabi?"

"Um..."

Hanabi Hanabi sat up from his lap and, amidst the sounds of the train, looked at him and said:

"Well... Hanabi will reluctantly agree to Kai-kun's request and sing him a birthday song alone while there's no one on the train right now."

"it is good."

Uesugi Kai agreed, and then, watching in the flickering light, Hanamaru Hanahime, her eyes smiling, sang softly, like a spring breeze caressing her ear:

Happy birthday to you! Happy birthday to you! Happy birthday to you! Happy birthday to you!

Kai Uesugi had been resting his face on his hand and his elbow on the back of the train, enjoying the sight of Hanabi singing to him, but then Hanabi suddenly stopped.

"what happened?"

"Isn't that a bit too childish?"

"So what if it's childish? Aren't all birthday songs the same?"

"No, there's another version we hear most often: Today is truly joyful, today is truly happy, happy birthday to you, let's sing together!"

Kai Uesugi laughed again: "I feel like Hanabi-chan would be perfect as a kindergarten teacher, she's really patient."

"I've thought about this fireworks too... Wait! Kai-kun, do you still want to hear it?"

"Yes, you can continue."

“Well… Hanabi continues,” Hanamaru Hanabi cleared her throat, then continued to sing to him with a smile, “HAPPYBIRTHDAYTOYOU~~HAPPYBIRTHDAYTOYOU~~HAPPYBIRTHDAYTOYO.”

"Pfft—hahaha, Hanabi's English is so bad! And she has such an accent!"

"Kai-kun is naughty! Hanabi even sang a song especially for you!"

"Sorry, sorry, I really didn't mean to mock you, but it just feels so weird."

"It's not Hanabi's fault that she can't learn English well!"

"Haha, isn't it all the fireworks' fault?"

"Kai-kun is so mean! Hanabi was actually quite touched! I'm going to hit you!"

"No, no, I know I was wrong, wife, I know I was wrong!"

"Oh, you still dare to laugh! I'll beat Kai-kun to death!"

"Hahaha."

The tram continued its journey home through the pitch-black night, while white snowflakes drifted down from the dark Tokyo sky.

###Chapter 549 Kai-kun's Birthday Party (The End)###

Living in Tokyo, all I want to do is laze around.

After getting off the tram, the cool night breeze blew under their feet as the two walked together along the banks of the Kanda River.

We arrived at the entrance of a detached house with the words "Hana Maru" written on it.

Kai Uesugi and Hanabi Hanabi stood at the doorway, where the same pot of lilies still stood. Snowflakes drifted down, and everything around them was pure white.

The two looked at the door of the Hanamaru family's house ahead, showing no intention of going in.

Kai Uesugi, holding Hanabi's hand, turned his head and smiled at her, saying, "Everyone's already waiting for us at home, right?"

"Hmm..." Hanabi Hanabi replied in a weak voice, "Does Kai-kun feel any anticipation?"

"I'm looking forward to it, but I'm also a little hesitant to go in... because I know there's a surprise coming, and I know I'll see it as soon as I open the door, so I need to be a little mentally prepared."

Snowflakes continued to fall from the sky; the snowfall never stopped on Christmas Day.

The light from the streetlights shone on Hanabi Hanabi's hair and small face, creating two beams of radiant light.

Kai Uesugi stared at her, mesmerized.

"Kai-kun?"

"Haha, it's nothing, I was just a little lost in thought while I was looking at you."

"...Kai-kun...Shouldn't you have already had enough of watching fireworks by now?"

"How could that be... I can never get enough of looking at you. I still clearly remember the way you walked out of the inner sanctuary wearing your white kimono."

Hanabi Hanamaru also recalled the scene of the wedding that day, when Kai-kun, who stood in front of her waiting for her, was quite handsome:

"Kai-kun, you really liked your wedding day, didn't you?"

"Yes, a day I'll never forget... When I was at the coffee shop, I would often take out the photos that my aunt and the others had taken and look at them... Yuuki would often laugh at me when she saw Hanabi with tears in her eyes."

"And what about Kai-kun?"

"what?"

"Kai-kun cried while watching the fireworks... was he laughing at her too?"

"Haha, I was laughing at her, laughing at how cute and innocent she looked when she cried. But as I laughed, I couldn't help but shed tears myself. Then, watching her put on her wedding dress for me, so many words were stuck in my throat. I wanted to say something, but I didn't know what to say. I just felt so moved."

"Kai-kun".

"Ah."

"Sometimes Hanabi has to admit... Kai-kun's sweet talk isn't corny after all!"

"Oh? Now you know how good I am? Do you want me to wrap up a whole bunch of balloons for you, write things like 'I like fireworks' on them, and release them into the sky?"

"I just praised Kai-kun, and he immediately showed his true colors! Writing 'I like you' and sweet nothings on balloons is so corny! But... if Kai-kun is sincere, even the corniest sweet nothings will touch Hanabi a little."
