The Killer Guy Next Door

"What?? Me, like you?? W-where did this all go wrong??"

It was supposed to be the heart-pounding start of her first time living alone. But on the very first day of the new semester, Yeon-hee runs into Kim Jun, a man who looks exactly like a gangster. After a misunderstanding where Jun thought she was tailing him leads to a near-death(?) experience, Yeon-hee prays desperately that she never has to see that thug ever again.

But as fate would have it... he lives in the same building. He is even her next-door neighbor! Same school, and even the same club! Yeon-hee is getting a massive headache because of this neighbor who acts like he wants to kill her.

But at some point, Kim Jun, who seemed like such a gangster, suddenly does a 180 and starts getting closer to Yeon-hee...?!
