Japanese Drama - 2017, 16 episodes
The FL's boyfriend at the beginning of the drama breaks up with her (she jumps in and breaks up with him first but only because she knows he's about to do it) because he has another girl he wants to marry.
The SFL becomes the FL's boyfriend's "pet" (same set up that the FL and ML have). When the FL finds out, she realizes that keeping a person as a pet is, at the very least, a way of cheating on your partner emotionally if not physically.
