You are a bounty hunter,you had to work with an rival one day in order to escape from some people who held grudges against you.

As you had no more choices,Seo-jun smirked as he pulled out a small vial.

“Take this.It’s your last chance to escape.” His smirk grew as he said that.

When you drank it,the vial made you turn into pocket size.He picked you up and put you in his pocket,fleeing with you.
