Persona 5 x Persona 4 Shitpost Crossover
It's post-canon P5R but before P5S. The Investigation Team are all around 20-22 with the exception of Teddie (he's mentally and physically 16). Yukiko and Kanji work for their family businesses, Chie's at the police academy, Yosuke and Narukami go to the same university in Tokyo, Naoto does detective work and Rise juggles being an idol on top of her online school work. All of them are out of Inaba with the exception of Yuki and Kanji, though the rest all visit when they can. Yosuke is packing up his stuff in his university dorm, preparing to head down to Inaba for golden week, when he gets a phone call from Teddie.
They get to talking and Yosuke feels himself smile hearing Teddie's voice again. He missed the guy. Yeah, he could be really annoying, but Yosuke did genuinely like him and his stupid jokes. It was a lot easier for him to admit that, now that they weren't living together and Yosuke wasn't an angsty teen anymore. He saw Teddie as a little brother and it was good to hear his voice. Yosuke zipped up a 2nd suitcase while asking Teddie why he called.
He could practically hear Teddie smile through the speaker. "I brought a boy home!"
Yosuke sighed. "You can't say that, man, it doesn't mean what you think it means."
"His name is Renren!" Teddie continued, ignoring Yosuke's reminder and barreling on forward with an explanation that Yosuke didn't ask for. This Renren guy was super cool, super pretty, ran around everywhere with a cat in his bag and thought Ted was funny (which the bear seemed very happy about). "He's with me right now! Say hi, Renren!"
"Yo," said a boy with a deep voice. He sounded like an Inaba local.
Before Yosuke could greet him back or react to any of the information he'd been given, Teddie continued at a breakneck pace. Apparently Renren was a bit of a coffee snob, had 4 part time jobs but not one at Junes because they refused to hire him, and scaled the Yasogami high building from the outside at 2 am last month so he could win a bet. A bet he made with Nanako, which Nanako did not think he would take seriously. Renren was a little worried about getting caught, since he didn't want to get arrested again.
Because apparently Renren had been arrested before.
"Wait, you said 'arrested'? Like, jail!?"
"Yeah," Teddie causally said, "Ren got arrested last year 'cause he pushed some politician, he was on probation for it. That just ended a few months ago!"
Teddie leaned away from the speaker. Yosuke could hear Ren say something in the background but he couldn't make out what it was.
Ted leaned back towards the speaker. "Also, he got arrested last Christmas for a different crime. So he spent two months in jail."
...This guy pushed a politician so hard he got arrested? Wasn't that physical assault!? And then he committed a completely different crime that Teddie wouldn't specify for some reason!? And got arrested again!? What, was he supposed to be some delinquent, or...an actual criminal?
"...Ted, are you alone with him right now?"
"Yeah! I said I brought him home."
"We're in Junes," the other boy said, with a deep voice that Yosuke now found anxiety-inducing, "It's closin' time, though. Just the two of us."
"Okay, I have an idea!" Yosuke squeaked without meaning to, "Teddie, why don't you call Nanako and go outside and just...uh, hang out there. Look at the sky, there's supposed to be stars out tonight. Just go outside."
"Your friend stays inside! He can look at, uh, the floor or something."
Yosuke heard the two boys laugh. Something about it made him angry.
"Nah," Ren said, "Not right now. I wanna spend some alone time with him."
"Well," Teddie said, "You heard him, Yosuke. I should stay with him. I don't wanna argue with my boyfriend, after all."
Yosuke let out a frustrated sigh. "Don't call him that, Ted, it doesn't mean what you think it-"
"Yeah it does," the criminal interrupted.
"I know what it means," Teddie insisted, "Renren's my boyfriend. We're dating! Isn't that awesome?"
Teddie offered no explanation, leaning away from the speaker to talk to his apparently boyfriend who was also a criminal. Yosuke dug his fingernails into his phone case until Ted eventually said, "Oh, I gotta go now, Yosuke! Renren wants to smooch. Bye, have a beary good night!"
Yosuke threw his phone to the carpet floor and nearly stomped on it.
Teddie was a little brother to him. Yosuke was very, very protective of his baby brother. He just didn't realize that until said baby brother admitted to dating a delinquent with a criminal record
