In the end both of them will die

It's the year 2345, it's 5 o'clock in the morning when you get a call from an unknown number. They tell you in a calm voice that 01/09/2345 will be the day.
You hang up without any emotion.

It's 5:05 when you realise that you got the call.

----

You're home alone, waiting for your boyfriend when you get 'the call'. You know that there's nothing to be done. But you don't want him to hurt, don't want him to experience this kind of pain, so your hurt him before he can get hurt way worse.

or in other words, it's the year 2345, technology has advanced so much in the past three centuries that scientists can tell when you'll breath out your last breath. And tell you they do, they call. They tell you. What you'll do with your remaining time is up to you.

There's only one rule that you cannot break. You're not allowed to tell anyone that you got the call. If you do so, you'll be eviscerated before your death day.

And in this mess, seven young men will meet. Through trials and errors they'll build a friendship so strong, even dead won't be able to separate them.
