Caution! Do Not Cross the Safety Line

Synopsis

During his student-teaching days, Minjae gave up his dream of becoming a teacher after an incident he’d rather forget. Now running his own café, he unexpectedly runs into Hyesung—his once-adorable student—at a class reunion.

Hyesung, now a screenwriter, has to write a sex scene but claims he needs some “hands-on experience.” His outrageous suggestion? “Date me for two months, teacher.”

A romance with a former student is unthinkable, so Minjae tries to push him away. But Hyesung keeps crossing the lines Minjae has drawn, edging closer and closer.

"This is my first time… so tell me, teacher, how many points would you give me?"

From the cute kid he remembers to a daring younger man who goes straight for what he wants, Hyesung is no longer easy to ignore. The real question is: can Minjae resist him?
