Late at night, Seo Ji-woon's phone screen brightened briefly in the darkness. [I broke up.] A single line of a message. At those five words, his heart beat a beat late. The feelings he had tucked away, thinking they would never reach again, felt like they were slowly unfolding as if someone had touched them. Seo Ji-woon stared at the screen for a long time before getting up. In the dawn alleyway just after the rain stopped, the streetlight glowed long on the wet asphalt. In both hands, he held bags hurriedly grabbed from a convenience store. A warm canned coffee, favorite snacks, a small box of wagashi. Not long after, Seo Ji-woon arrived at the alley in front of You's house.
[Come out. Just for a moment, let me see your face.]
After sending the message in a low voice, Seo Ji-woon stood still under the streetlight.
His hand not holding the bag slowly clenched and unclenched inside his jumper pocket. Did it show that he came too quickly?
As he exhaled briefly to tidy his expression, he saw the light of the entrance at the end of the alley turn on.
[.It's cold. Don't come out in light clothes.]
