Consider this to have happened before Unova-2 began.

At Hikari's

Sakura, Lyuri and, of course, Hikari were at the latter's home, drinking tea in the living room.

"So, what brings you two to my place?" asked Hikari, taking a sip of her tea.

"The fact that we're friends?" replied Sakura with another question

"Good point." said Hikari, giggling a bit.

"That and it seemed like a good place for our Pokémon to spend some time with others without any issues." said Lyuri, also taking a sip of her tea.

"Also a good reason." said Hikari, giggling some more.

"Hope you don't mind us staying for some time." said Sakura.

"Nope, I don't care at all, it's good to have some human company sometimes." said Hikari, then glancing at one of her videogames "Anyway, any of you want to play a game?"

"I'm in!" said Lyuri, looking rather excited about

"I... I'm going to sit out of this one, I think I'm gonna prepare something for our lunch instead." said Sakura, not looking very pleased with the idea.

"Are you sure? I can prepare it myself later." said Hikari as she was already picking the controllers.

"Yes, I don't mind, after all I like cooking." said Sakura as she began to head to the kitchen.

"Well then, better for us then." said Lyuri, quickly catching a controller that Hikari threw to her.

Sakura then went to the kitchen and from there she could hear as Hikari and Lyuri played, they seemed to be playing a fighting game, that alone was enough to make Sakura smile in amusement, not too long after she started cooking she took a quick pause to see how the game was going, it seemed like Lyuri was getting beaten, mercilessly.

"... Hikari?" asked Lyuri, with a bored look

"Yes?" asked Hikari, who at least seemed to be enjoying it.

"You know what the fun of a game is?"

"Hm?"

"Being able to play it instead of watching as you're combo'd to oblivion." she answered with a deadpan expression and voice as she was lightly swinging the controller on her hand as she watched as Hikari finished winning for what was possibly the third time in a row.

"Oh, sorry." said Hikari, with an awkward giggle.

Sakura herself could only giggle and smile at the situation as she went back to cooking. Not too long after it she looked again and saw what was pretty much the same result.

"Hikari?"

"Yes?"

"Just because you're now killing me in two combos instead of just one isn't making it any more fun."

"... Maybe we should play something else?"

"Agreed."

Sakura once again giggled and smiled at the scene and went back to cooking, this time however, she didn't let anything interrupt her as she feared that if she did she'd take too long to finish what she was preparing.

"I know better than playing videogames with Hikari, sorry sis, but better you than me." Sakura said to herself, giggling.
