A Promise, I think?

Sakura Park
-Earlier-
1:40 PM

After Kagura and Sougo fought, they sat down on a nearby bench beside a sakura tree. "You did get stronger, hm" sougo sighed as he tilt his head backward on the bench. Kagura was petting sadaharu while he was still on his small-sized version of him, "Hmph, of course I did, but if I'm going to be honest, if you didn't train at all, it won't be a tie and I'd win already", Kagura said, Sougo chuckled and looked at her, "that's a good way for you to hide your acknowledgments to me", Kagura looked at him back, "what's that supposed to mean?" She asked knowing what he meant.
..
"Here", Sougo hands out to Kagura her other ornament. Kagura was surprised, "I'm surprised you kept it til now, I thought you'd slash this into pieces just to mess with me" she smiled as she took her ornament and kept it beside her, "Hm, well you didn't believe me when I said we were coming back, you were even making fun of me at that moment. I guess I win" Sougo looked up and shut his eyes. "So you had to take this from me", "well you gave it to me in the end.", they both grinned. "at least before you guys left, we said bye to each other "properly" without fighting", "can't say the same," I was disappointed, though, Sougo thought.

-flashback-
At a nearby river
"You're leaving earth again? Are you guys too insecure about yourselves or something?" Kagura asked Sougo. They both bumped into each other earlier. "We received an invitation from a trustworthy amanto since we saved most of their kinds before and they wanted to offer us a training course on their planet for more than 2 years". He explained. "is that so? Don't worry we will take care of this place with you guys gone, although you were useless from the start" Kagura murmured the last part but Sougo heard it. He walked towards Kagura while intimidating her, "Don't worry, if you're going to miss me that much, then I'll gladly let you know that I'm going to come back stronger than you this time" he stopped walking when he was closer to Kagura, teasing her. Kagura glared at him for a bit, "in your dreams, sadistic bastard. I'm not certain about this" she responded.
Sougo smirked, he wanted to mess with her for a bit, but he thought it wasn't the right time. Even with all of their insults to each other, they still... care about each other? Or maybe because they've known each other for so long. They were both feeling things they weren't familiar with. "If you don't trust me about that then let's make a bet" Sougo wanted to call it a promise, but it was a weird thing to say to her.
Kagura raised a brow, "a bet you say? What is it", "hang on I'm still thinking.. Give me your hair thingy", he pointed at her head. "Wha- you mean my ornaments?", "Yeah, just give it to me.", "are you going to burn it?" she exclaimed, her dad gave her the pair of ornaments she was wearing before she came back to earth, so she was stunned about what Sougo just asked her to do.
Sougo sighed, "Relax, China, I'm not gonna do anything to it, just give me one of those, if I come back here with that in good condition, then I win and vice versa" he looked at her with soft eyes, Kagura hesitated. She smirked and handed Sougo one of her ornaments, "you don't have to bet anything, just give it back to me in one piece or I'll kill you."
And they parted.
-End flashback-

Kagura looked at her ornament and thought about something. "We both didn't change a bit. three years already passed, it's unbelievable, I'm sure the others also didn't change" She smiled. Sougo looked at the sky and grinned.

Kagura opened a new sukonbu packet and took a piece of sukonbu to chew on. Sougo noticed it, "3 years and you're still pig woman" he smirked, a mark on Kagura's forehead appeared, "Who are you calling a pig? You know, 3 years and you still being a prick is not even surprising anymore! Shinsengumi Vice chief, more like Shinsengumi's whole joke" she exclaimed. Sougo also had a mark on his forehead and got quite irritated, "look who's talking" he responded. Both of them glared at each other and started attacking each other on the bench. "You, a woman? Heh, you're still the same pain-in-the-ass brat", "shut up you damn brat! Just because you showed up looking like a damn mafia boss doesn't make you look intimidating you bastard!".
Both of them were pushing and holding tightly on each other's hands. Sadaharu got off the bench and grew bigger again, Kagura stopped and walked towards Sadaharu. "about that dog, what happened to him?" Sougo was curious, "when he came out of the shell he was in, it gave him this kind of ability. Weird isn't it?" Sougo looked at Sadaharu while Sadaharu barked. "Well, I have to go back, This was an unexpected day but, see you around, Sadist." Sougo smirked, "that's the first time in 3 years I heard someone call me that before.", "aren't I the only person who calls you that?" She said. "Is that so?" he said teasingly, kagura noticed his tone and was embarrassed so she blushed a bit and looked away from him. "Whatever! I'm going home, you should better go too, didn't you just arrive yesterday? Not that I'm concerned" she winced as she looked away from him "petting" sadaharu. Sougo looked at her with a brow raised and a smirk on his face, "Go ahead, I'm just going to rest my eyes for a bit".

-Yorozuya Residence-
After Gintoki, Hijikata, Shinpachi, and Hajime meet
4:50 PM

Shinpachi and Gintoki entered their home while removing their shoes on the entrance. "welcome back" Kagura greeted. Gintoki looked at her as well as Shinpachi, "same with you, welcome home, so did you buy the shampoo I asked you to?" Gintoki asked. Kagura's eyes widened, "I forgot!", Gintoki grinned, "heh, I guess you were busy".
...
Gintoki sat down and turned on the tv. Shinpachi pretended to cough to remind Gintoki about the situation. Gintoki looked at him and then at Kagura. "we got a job request by the way, and it's going to be hard", Kagura looked at him, "huh? That's not a problem" she shrugged and continued to watch tv. "We're going to Yoshiwara tomorrow, our client lives there", Kagura smiled, "that's perfect, I just heard from Tsukii that there's a new bakeshop there, we should go check it out tomorrow".
...
"Kagura did baldy mention anything to you in your letters.", kagura raised a brow, "not particularly?", Shinpachi sat properly, "Gin-san, I'll explain everything to her instead." Shinpachi told him. "Explain what?", "about our client and her job request" Gintoki answered.
