The front door clicked open as Suki stepped inside, backpack slung over one shoulder. Auntie Mina’s engine revved outside, but she didn’t come in—just a wave and a “See ya later, kiddo!” before pulling off.
Suki was supposed to be happy. Half-day at school. Hero internship next week. Mom said he could pick dinner.
But all of that vanished the second he stepped into the living room.
There was a woman on top of him—smirking, messy-haired, lipstick smudged across her arrogant face—and they were kissing. Not some quick peck, either. This was full-on, hands-wrapped-around-her-thighs, mouth-on-her-neck kind of kissing.
“...What the hell?!” Suki shouted, dropping his bag with a thud.
Katsuki pulled back—barely. The woman laughed like nothing happened, brushing a hand through her hair.
“Wow,” she sneered. “You didn’t tell me your brat had no manners.”
“Old man,” Suki growled, voice sharp and loud. “What the actual hell is this?!”
Katsuki sighed like he’d just been interrupted from something important, not like he was caught cheating. “Calm down.”
“Calm down?!” Suki yelled, sparks already flaring off his palms. “You’re cheating on Mom! You’re making out with her on the couch!”
“Watch how you talk to me,” Katsuki snapped, not moving from the couch, one arm still casually draped over the girl’s legs.
“I’m talking to you exactly how you deserve,” Suki shot back. “You think I’m stupid?! You think I don’t know what this is?!”
The girl rolled her eyes. “Ugh, he’s dramatic. Just like his mom. No wonder you needed a break from that woman.”
The air snapped.
Suki’s head whipped toward her. His voice dropped, deadly. “What did you just call her?”
“She said—” Katsuki started, raising a hand like he was going to shut it down.
“Don’t,” Suki snarled. His fists lit up, tiny pops and crackles echoing around the room. “Don’t even try to defend that. Say it again, I dare you. Call her that one more time.”
“She is just a woman—” she scoffed.
Suki’s palm exploded in a small, sharp blast, inches from the coffee table. It scorched the edge.
“She’s my mom,” he growled. “Say it right or shut the hell up.”
Katsuki stood slowly, stepping in front of the girl like a shield. “Suki. That’s enough.”
“That’s enough?!” Suki’s voice cracked, not from weakness, but fury. “You’re gonna stand there and protect her?! After what you just did?!”
“She’s not some random chick,” Katsuki said through clenched teeth. “This’s been going on for a while.”
Suki blinked. Like the floor had just given out under him. “...You’re not even sorry.”
“I didn’t say that.”
“But you didn’t stop, either,” Suki said, pointing. “You saw me walk in, and you kept going. Like I didn’t matter. Like Mom doesn’t matter.”
Katsuki ran a hand through his hair. “You don’t understand. Things with your mom—”
“Don’t say ‘woman.’ Don’t even try,” Suki warned.
Katsuki gritted his teeth. “Fine. Things with your mom haven’t been great.”
“Then fix it,” Suki said, voice trembling now. “You don’t throw her away. You don’t bring someone else into our house. What the hell is wrong with you?!”
“She gets me,” Katsuki muttered.
“She’s using you,” Suki snapped, pointing to the girl still lounging on the couch. “She doesn’t care about you. She just likes bragging that she’s screwing a Pro Hero.”
“Watch it.”
“No!” Suki shouted. “You watch it! You made me this way. You told me not to let people walk all over me. To protect what matters. To be loyal. And now you’re just... like this.”
The girl stood up finally, wrapping herself around Katsuki’s arm with a smug grin. “He deserves better. And you’ll get used to me, kid.”
He dropped his arm and spoke low and cold. “You’ll never be my mom. You’ll never be good enough. And if you ever call her ‘woman’ again, I swear I’ll blast you so far across this city, Recovery Girl won’t find your eyelashes.”
“Enough. You’re grounded.”
Suki laughed bitterly. “Oh, I’m grounded? You’re the one cheating, and I’m grounded?”
“I don’t talk to traitors,” Suki said. “And that’s what you are right now, old man. You betrayed Mom. You betrayed me.”
