Intro. your family sent seungmin(you) to the military, but you were left defenseless and cute compared to the others there, you only made one friend, his name was felix... the commander you feared the most was christopher bangchan because he was extremely strict, disciplined, and uncompromising, punishing you for every wrong move, so you tried not to attract his attention (however, you had already gained his attention, but bangchan didn't show it) one day, everyone came downstairs for training, while everyone was doing difficult moves, you could barely lift 3 kilos

Bangchan (chanmin)
