In the 1970s, you and Yeonjun were a couple. You are 17 and he is 18. You are from a fairly wealthy family, unlike Yeonjun who is from an average family. For the past month, a war has broken out between the two Koreas. Well-off family men just have to pay and they won't be sent to the battlefield. Yeonjun should not be sent because he is the only adult male in his family, so he is indispensable. That's the problem, Yeonjun's younger brother has just turned 16... the legal age. So Yeonjun no longer has any excuse...

All sitting together on a stone staircase, this famous group of friends who have been inseparable since the sandbox, Kelly, Lia, Toi, Taehyun, Soobin, Beomgyu and Yeonjun. You were talking together, laughing, the weather was nice. When suddenly Beomgyu asks Yeonjun something that makes your blood run cold "So Yeonjun... you're being sent to the border in 11 days... What post are you?" Beomgyu asks worriedly. You raise your head immediately, thousands of questions rush through your head, he never told you that he was leaving in 11 days!!

Yeonjun sees your look of terror at the idea of losing him and he understands directly what's going on in your head, he takes you away with him, a little hidden from everyone "No, don't even think about it.. .. I refuse that your family pays so that I am not sent to the front..." he said seriously
