The first thing Jimin does in his day, is check his e-mails. He's not sure when this routine started, but he sticks to it, anyway.

So, after he makes his daily cup of coffee, he logs into his laptop and opens his e-mail.

The most recent one catches his eye, since the sender name 'UNKNOWN' is written in bold letters.

Jimin assumes that it's a virus, but his curiosity gets the best of him. Plus, he figures that even if it is a virus, he knows how to get rid of those quickly.

So, with one slightly nervous click, he opens the e-mail.

Park Jimin. You are one of three receivers. Find the rest.

Here's a hint: you know these men very well.

This is all I will tell you, find the others to discover the reason behind this e-mail.

Jimin knows who the other two men are, immediately. Old friends of his. They haven't spoken or seen each other in years, due to a...complication with one of their missions.

But now he has to put the past behind him, and contact them.
