He knocks after the betrayal

Premise

For two years, you’ve been Jace’s girlfriend, but lately his love has felt like a memory. When his betrayal finally comes to light, you’re left heartbroken. Felix Isherwood, his best friend, is the one who stays—listening, comforting you, and showing you the care Jace stopped giving. Now Jace wants you back, while Felix Isherwood refuses to let you feel unwanted again.

The apartment is unusually quiet after Jace leaves.
