What if?

S/n?!

2 months later

Y/n was going to the store with s/n because she needed to make dinner. She had been doing online jobs which were easier for her to take care of s/n. Although she was still young, especially to go to college. She just wanted to be there for her son, s/n was going to kindergarten in 2 months and she wanted to be there for him. 

"Mommy, do you think that the kids at school will be as childish as you?" S/n said.

 He was holding her hand while walking to the store.

 "Haha sometimes I really wonder if you're my son," Y/n said giggling. 

"Maybe I'm like my dad!" S/n said cheering.

 Y/n's eyes widened, "We don't talk about him here." Y/n said. 

I mean s/n is pretty mature for his age. I just want him to enjoy his childhood. He is really like Atsumu though that one time in the playground when he disappeared he really worried me.

"Okay, which one of you jerks try to force my mom?!?" S/n said angrily.

 "You shouldn't have s/n." Tanaka said worriedly.

 "Don't worry Uncle Ryu I got it." He said confidently.

 "So which one of your names is Erice?" S/n said stepping up. 

"what do you want little punk?" a brown hair guy said, stepping in front of him.

 "What the f*** you're literally 4." That man said.

 "Watch your mouth old man, that's called ageism. You assumed that I won't be able to do anything just because I'm four? Well, remember the drugs you tried selling? Well, the police will be here anytime now." s/n said looking at his small watch on his hands. 

Then the siren started going off. 

"OH shit run!!, You BASTARD I'LL GET YOU BACK!" He said running. 

"HAHA omg, s/n your plan really worked MY GUY!!!" Tanaka lifting up s/n.

 "Oh thank you uncle ryu, uncle Daichi!!" S/n said jumping down and walking towards Daichi.

 "I can't believe that actually worked, I told the other sheriffs to go to his house but s/n how did you know where he lived?" Daichi asked, 

"Honestly both the police officers and criminal are dumb," S/n said crossing his arms.

Both Tanaka and Daichi were shocked.

 "You see that Erice put his address on the box of drugs. Dumb..dumb as a carrot." S/n said sighing and walking out of the ally. 

Daichi and Tanaka snickers and walks out of the ally after s/n.

 The next day s/n was in the playground with y/n/ Y/n was just talking to Kiyoko about putting s/n to school. Then Erice, the guy from yesterday who tried to force y/n came facing s/n right in the eye. Y/n was busy talking to Kiyoko but Kiyoko saw him. Kiyoko gave thumbs up to s/n and s/n smiled. 

"Can we not make ruckles here because if you kill me here everyone will see you but let's go on the ally shall we?" S/n said walking away.

 "Making out jobs easier haha." Erice said following s/n. 

They were in the alleyway and s/n stopped on his tracks. 

"Now little punk! you'll regret what you did yesterday." Erice said. Then s/n lifted his head and said, 

"You all can come out now." 

Then a group of police officers including Daichi had surrounded Erice's team. 

"YOU-"

 How many times are you going to be foolish, if you can't even beat a kid then don't call yourselves criminals," S/n said and walked back to the playground.
