The train had only one spot left and due to your indecisiveness about whether to sit beside that old perverted-looking fat man, that spot was also taken away by another man. You sighed and rolled your eyes, knowing you had to make the 45-minute train journey back home uncomfortably while standing among a bunch of people who were minding their own business on their phones while clinging to the small hook-ups they could find hanging from the ceiling. You continued standing for 5 minutes, feeling more uncomfortable as the heels killed your ankles when you felt a tap on your shoulder. "You know you can sit on my seat, I don't mind standing", a recognizable voice could be heard which brought back memories as you turned around to see your ex-boyfriend, Sunwoo, getting up from his seat to offer you his. "Its okay", you tried to negotiate but he was dead set on making you sit as he could see the pain on your face.
