Two different worlds

Sero woke up the next day and got dressed in his old clothes, walking quietly downstairs and quickly to the front door. Kaminari was up bright and early and was on the couch laying down before he seen sero go to the front door “where are you going?” He asked. Sero squeaked and quickly ran into Katsuki's room, jumping on his Daddy and hugging him tightly. "DADDY WAKE THE FUCK UP!!!" Katsuki groaned and looked down at sero “hm whats wrong?” He hummed out as he held his little close. Sero sniffled and shook on the whole body. "KAMINARI IS DOWNSTAIRS!!! THE FUCKING HELL!!!" Katsuki had gotten up and stretched as he went downstairs and asked kaminari why he was here and was kinda shocked at his answer apparently kirishima had broke up with him and kicked him out for what he pulled yesterday. Sero ran downstairs and hugged Katsuki's leg, not letting go. "I would have done the same if I would be Kiwipima...." Katsuki looked down at sero “that wasnt ok of kirishima i know that he did something wrong but you never do that” he spoke out. Sero shrugged and walked to the kitchen, making food and walking back. "But it's still not okay when I tell him to stop and this a few times!" Katsuki sighed “well obviously but still he shouldn’t have been kicked out” he spoke out. Sero sighed and frowned as he sat down and ate. "Then go and beg. I don't care what you do but when you stay here, I will go and I'm serious." Katsuki groaned and took out about a million dollars out and handed it to kaminari and had him leave to go find a house. He looked at sero but didnt even say anything. Sero just ate and turned the tv on. He didn't care about what they both did. Sero really was extrem bratty and annoying when he wasn't a little. Katsuki had turned the tv off and glared at sero “I know what he did but you didnt need to be an asshole about it”. Sero groaned and finished eating. "I'm not an asshole. I'm just saying that I don't care about him. I don't even understand why you gave him so much money." Katsuki looked at sero with an unbelievable look on his face “You were being an asshole, you didnt want him to stay with us so i gave him money to buy his own place.” Sero laughed in a selfish way. "It's a normal thing that I don't want the person thst rapped me to stay in the same house as me." Katsuki scoffed “theres a thing called separation, there are multiple different guest rooms plus its not like you live here i only brought you here just to make sure you didnt catch a fucking disease from how much a slut you are” he snapped out as he walked upstairs to his room and slammed the door. Sero walked upstairs and opened Katsuki's room, slapping his Daddy. "I'm not a fuckin slut! I just try to get enough money to heal my parents who have cancer!" Katsuki just stared at him “Well there are other fucking ways you can get money instead of being a whore” he spoke out. Sero hissed and grabbed his things. "Fine! When I'm a 'whore' or 'slut' like you say then you won't care when I leave!" Katsuki rolled his eyes “fine go find another dom who’ll fuck you in little space nasty bitch” he shot back as he laid on the bed. Tears rolled down Sero's face. "Fine... When you don't want me anymore then you can get Kaminari." He walked out of the room quickly and fast to the front door. Katsuki was gonna know how bad he fucked up in the long run, but right now he just kinda laid there not feeling anything. Sero opened the door and slammed it behind him. He just ran to the next bus station and took the bus, driving home.
