You have a huge crush on your brother's best friend.

It was always so obvious.

Well, you guys don't really talk much, but you could say you're friends.

Right now, you and your brother sunghoon are sitting together, watching a movie.

Suddenly, some messages pop up on his screen, and you can't help but glance at his phone.

One of the messages is from heeseung.

He's wishing sunghoon a happy birthday.

Today is your birthday too — you completely forgot.

You know you won't get any messages from him, but a little hope lingers inside you.

You lay on my bed when you hear your phone ring.

Your eyes widen at the text; how does he know you were born just five minutes after ur twin brother sunghoon?

“Happy birthday, sweetheart,” it reads, exactly at 00:05 AM.
