My brother best friend / Bruno x Reader (patito feo-patty )

Hello everyone, this is my first story. I hope you like it.

Matias has a sister, y/n, who has just started going to his school. But y/n will fall in love with her brother's boyfriend, what will happen, will he love her too??

If you know Greek I suggest reading the Greek version that I've cause it's better. This was one of my first stories and my English back then weren't that good.

Enjoy!
