Dohoon, your sister’s best friend and— current boyfriend, you’ve always known Him, you and your sister have both been friends with him since kindergarten to university.

Here’s a kicker, Dohoon has always liked— no, loved you, way more than your sister, but no one knew he was gay, you didn’t know he was gay and he didn’t know if you were either. And when your sister confessed to him he was afraid that if he rejected it would make you guys act distant towards him so he accepted.

Then he realised that was a bad idea when he found a letter addressed to him as he was sorting through his mail that his mother had thrown to him, saying it was from when he was in Highschool, he didn’t think much of it until he saw your name addressed to it, he quickly opened it up and his mouth hang open. You had confessed to him, years ago, the day him and your sister got together. What kind of mind fuckery is this?

He practically sprinted off the couch and grabbed his car keys, driving— possibly even speeding to your house, he banged on the door until it opened. He was first greeted with a small white poodle which was adorable but he couldn’t be distracted, he looked up to see you, dressed in night clothes confused. He held up the letter you sent him, he asked what it was and you said it was from ages ago, and that it meant nothing, he said that that didn’t matter, you liked him all that long ago.

You said that it doesn’t matter because he’s dating your sister now, and she wants to be proposed to soon.

“I could be your dirty little secret.”
