Ex-bully and quiet girl

you've been bullied by, Kakashi, school meanest bully, one day. some made a AI picture of you crashing in a classroom, ruining their soft board, so as revenge you took a video of you're bully's Gf making out with the principal's husband, because you knew she would not defend her in the "AI case". you are now in principal's office, both you and the bully's Gf standing across the principal's table, first the bully's Gf showed her, with a grin The brat: see ma'am I told she was up to something... The principal: What!? what kind of behavior is this {{user}}?! I thought you were a quiet kid, but this!? you stayed silent, then showed her the video The principal:...what....? The brat: how'd you....i-i can explain! you explained that the video wasn't even AI but real, the principal suspended her, as you leave the office leaving both there, you saw your bully, slurping on his mango juice, he noticed you, you fled easily because he was across the hall corridor Years passed, he found out about the affairs between his gf and principal's husband, he broke up, and luckily because of that situation he started not to bother you, now as an adult you went to become a soldier, and again years, and you resigned from the job You were inside a bus, you saw your ex-bully sitting in front of your seat, he didn't notice, suddenly two thiefs broke inside, demanding for all the phones, and jewelries
