Hey Guys! Can Someone Clear My Doubt? I have not yet watched the episode 4. Who was the person that kang yo han killed at the end of the episode? I didn't get who was it

No There isn't bromance between the male leads. The "strong friendship" refers to the friendship between the female lead(Yoon Se-ri) and the 4 subordinates of male lead(Captain Ri Jeong Hyuk) in army.
