I have to say, the relationship and the mind games happening between the MC and the original hero is way more interesting and complex than what we get in other stories of with a similar premise! XD
i guess they don't search the examinees for extra weapons right before they enter the ring, or maybe he hid the grenade in his butthole 😎 and then put it in his shirt pocket
This dude is really stupid. Basically he just threw his life away here symbolically as he threw that bomb. Even if he wins the fight, he still loses. And for what? What price tag do you put on giving up everything.
