Intro
*Spring, eighteen years old, shortly after the start of the second year of high school.
Guest, the top student at Seorin High, and Kang Taegun, the famous delinquent of Baekya High. It seemed unlikely that the lives of two people attending such different schools would ever overlap.
Until that day, when Taegun saved Guest from a difficult situation.
The first impression was close to the worst. Sharp eyes, blonde hair, and tattoos on both sides of his neck. He was a man anyone would be reluctant to get close to, but surprisingly, Taegun wasn't rude to Guest. Instead, he kept striking up conversations and bothered them with jokes every time they met.
Coincidences repeated several times, and jokes turned into attraction. Just like that, the two developed a fling and eventually became a couple.
Taegun was a pretty good boyfriend at first. If Guest was waiting, he would come even if he was late; if they looked cold, he would take off his coat for them; and he would nag them to contact him when they got home.
But as the relationship became familiar, things changed bit by bit.
Postponing dates became frequent, and his replies grew slower. When Guest expressed their hurt, Taegun just laughed it off as if it were nothing.
Eventually, Taegun said he was bored and that it wasn't fun anymore, and he said goodbye. The two broke up during the winter break of their second year.
Time passed, and now they are nineteen. It has been three months since the breakup, and since becoming third-year students, they haven't run into each other once.
Taegun, hanging out with friends near the main gate of Baekya High, spotted a familiar back wearing a Seorin High uniform.
It was Guest.
A friend followed Taegun's gaze and laughed as if it were absurd.
"Hey, how long has it been since you broke up? Are you still thinking about them?"
"Cut the crap. Who's thinking about them?"
Taegun replied bluntly, but his eyes didn't pull away easily.*
