My little brother became the hero and I a villain

" ( The prophecies hero ? Their last hope ? What- what the hell happened just now ? I'm not dreaming am I ?Those people- No, there's something more important than that- the hero…….if what they said is true, if all of the things we just saw was real- then that means the hero is among us, Urgh- My head is hurting so bad, it hurts, I should have stayed home today, even if I sleep all day, it's still better than getting headaches from time to time. ) "I thought to myself and then checked my phone.[Message notification]From- Mom[ Cain, where are you ? Did you get the eggs and milk from the store ? ]From- Dad[ Why is it taking so long for you to come home ? Do I need to remind you what will happen if you don't get home before 7pm ? ]" ( Seriously, he should be grateful that Mom is such a softie, otherwise I would have kicked him out of the house already, he's such a waste of a human being. ) "I thought to myself in anger.That's right, I don't have a great relationship with my so

"I said to the old man while stopping him on his tracks," Boy, I appreciate that you want to come and take care of our hero, but this is no small matter, and don’t you dare say you want to tag along just because it would be fun to be at the side of the hero and adventuring with him, you may be the hero's bro

"Oh….so this is what Geraz was talking about, well it's not like this will be a real pain in the butt for me……yet that is, guess I'll play along, " Yes of course, like Geraz-sir said, I'm only here for my brother alone as it wouldn't be right for me to leave him all alone oh and I don't plan on being a nuisan

Right after we entered we were seen by the emperor and he then called for us," Hm, welcome yuusha and cain you too, the esteemed guests will be arriving in a while so both of can familiarise yourself with the people that are here right now,Yuusha you may come with me, we have got people from the south that wanted to see you,Cain, you may….umm….go and relax yourself while both me and the yuusha will be back in a while,As for the maids, you both can stand at the corner and wait till we come back,Let's go now yuusha. "The emperor said and then went with Rei to the people that were waiting for him,Both Penelope and Rei's maid went too," *sigh* And now I'm left all alone…….I should probably get some fresh air outside, this whole….suit like clothes may look cool but they are kinda uncomfortable for me to wear and even hard to move in.
