Betralay { Kou Mukami x Reader }

Kou Mukami. You're favourite idol. You had been one of his fans since the very begining. Everytime a new album came out, you'd buy it.

The best/worst part about this was that you both attended school together. You were in all of his classes and he knew exactly who you were. He adored you, in fact. That's why he asked you out.

You were delighted. You were even more delighted when you found out you would be living at the mansion with him and your friend Yui.

But when you find Kou with his arms wrapped around Yui and his head buried into her neck, you can't help but feel your heart break.

Was this betrayal or something much darker?
