Male OP Reader x hero killer webtoon harem

prologue

In place looking like abandoned building when we see a old man wearing a combat training outfit sparing with a white hair boy with coloured eyes breathing heavy and then smirks

White hair: sensei training with you is really helping me get to control my energy (also known as EST)*am really approving with my gift*

I said looking at my hands, but then Sensei blitz me,me losing focus

Sensei:Boy never lad up when your opponent rushes you when your not focusing

We were training non stop until midnight we took a break,I was looking at the stars in the sky when my Sensei was walking towards me

Sensei:Y/n you want to go to Korean for the hero training exam

Y/n: Yeah after I lost parents and getting this my powers I wanted to be hero seen I couldn't save my parents from my house when my gift activated that accidentally cost the house on fire till this day I regret creating fire in my mind, thank you Sensei for looking out for me all those years, to be honest i think should be alive after that day

Sensei: nonsense you deserve to live, that why I took you in so you can survive and fight what wrong*sigh*be careful out there especially the hero clan and the villains,i don't like what the heroes are doing especially the elders

Y/n: I really want to meet the the number superhero*smiling*

Sense: yeah yeah you fanboy,like I said be careful out there

Y/n: yeah sensei*smiling looking at stars* I going to stronger to protect anyone and safe people and defeat my enemies who stand in my way*determined look*

Sensei: That is what I like to hear*proudly smiles*'he look at the stars as you*

Morning

The airport when we see people walking around the place,then we see you and your sensei in the corner of the door to the airplane

Sensei: this is it

Y/n: yeah this is it

Sensei:am proud to see you grown up
But that doesn't mean your training stop,you will keep going and going until you surpassed your limit

Y/n:*deadpan look*yeah yeah*sigh*bye sensei thank you for putting me underwing and until then see you soon

Sensei: yeah see you when our path crossed

He hugged you and you hugged back and you left in to an airplane and took flight to Korean, you were resting with headphones on listening to your (favorite music),as sensei was walking home he said in his mind "be careful you got a lot of work to do, chose your path carefully

That'll all till next time 😁
