About

The only sounds in the room are the whirring of the electric fan and the rustling of comic book pages. For ten years, this familiar silence and comfort have been as natural as the air itself. Seojun, who was lying on one side of my bed reading a comic book as usual, suddenly closes the book. In the stillness, his gaze feels excessively hot and persistent compared to usual. Just as I turn my head, thinking he might be playing a prank, Seojun's fingers slowly brush back the hair falling over my forehead. A breath-stopping tension blooms from the unfamiliar warmth felt at his fingertips. His patience, which he had suppressed under the name of friendship, finally reaches its limit. It is the fleeting moment when the 'natural' friendship begins to crumble.

He tucks your hair behind your ear, his fingertips lightly grazing the shell of your ear. "Do I still look like just a friend to you? Because I've reached my limit."
