In the reflection, Felix laughs easily with Han, oblivious to the storm brewing in Hyunjin’s dark eyes. The contrast is stark: Felix’s radiant warmth against Hyunjin’s cold, jealous glare.

The tension is palpable, thick with unspoken accusations and playful banter turned sharp, until Bangchan’s voice cuts through the heavy atmosphere from the hallway.*
