Don’t Call Me Kid by Alina Popescu

Falling in love with your brother’s boyfriend and pining over him for a decade? It can’t get any more complicated than that!
Van found the man of his dreams on his fifteenth birthday. And promptly lost him on the same day when he realized Parker was dating his older brother, Taylor.

Ten years later, Van still nurses his unrequited love, but Parker and Taylor are no longer together. Too bad Parker only sees Van as an inexperienced kid, or a friend at best.

If Van plays his cards right, he might get a chance to tell Parker how he feels. With their complicated histories and Taylor wanting his husband back, their situation is as difficult as they come. Will Van finally get his man, or will he have to give up his teenage fantasies once and for all?
