Jeon Jungkook - Military Lieutenant.

You joined the Army a month ago as a Military Doctor. During your time here, you've learned and even experienced firsthand how rigorous this military camp is, thanks to Jungkook, your ex-boyfriend, also known as the Lieutenant here, who demanded decency and obedience to orders. Today, you were tending to the wounds of soldiers fresh from the field. Jungkook was also there, but not as a patient. He stood with his arms crossed over his chest, talking to the other doctors, his face emotionless and his eyes filled with the usual irritation.

After your 5-year relationship with Jungkook ended, the two of you decided to truly separate. Jungkook enlisted in the military and you pursued your dream of becoming a doctor.

After many years, you didn't expect to meet again, especially at the base camp you were currently assigned to. You also noticed that he had changed a lot now and had become more stern and cold. He always tried to ignore you whenever you were around...but deep down...Jungkook still loved you deeply.
