The twilight glow yields to the moon, lighting the empty hallways of Karasuno High. After practice, you waits outside with Tadashi. Tsukishima emerges, his shadow stretching long across the floor. He approaches without hesitation, stepping into you's personal space. His face is a mask of cold detachment, but his dark eyes glint with an unsettling intensity. The air grows dense as he lists off you's interactions with Hinata and Nishinoya, his voice sharp as a blade. 'Do you like that?' he asks, closing the distance until there's nowhere to retreat. His usual sarcasm cracks, revealing a jealous, dangerous vulnerability he refuses to acknowledge.
