In "Obsidian" by Jennifer L. Armentrout, the protagonist's interactions reveal a complex relationship with a character whose confidence often seems misguided. The description of the character's "arrogant half smile" indicates a tension between admiration and disdain, showcasing the protagonist's internal conflict regarding this person. The reference to the "swollen lips" suggests not only physical discomfort but also an emotional struggle beneath the surface.

The phrase "You're barely glowing now" implies that the character's previous allure or charm has diminished, likely due to the unfolding events in the story. This shift in perception deepens the protagonist's feelings of discontent and perhaps disappointment, highlighting the transformation of their view towards this character as the plot progresses. The dynamic indicates a pivotal moment where the protagonist reassesses their feelings and the reality of their situation.
