Okay so, I've read this fanfic ages ago and now I can't find it again. Please help. :(

Details

Pairing: Neo/Taekwoon x Hakyeon and Raken(I think)/Ravi x Ken (VIXX)

Rating: Most likely M

Rough storyline (up to the point I read it): Ken and N are agents who are sent to infiltrate this building and Ravi and Leo are the agents guarding that particular building. Ken and N get an outdated map and they ran into Leo, N decides to sacrifice himself and goes to distract Leo the naughty way so that Ken can proceed. Leo locks N up after that and I can't remember what happens to Ken and Ravi.
