Han Eunsoo, the little rascal who has been my next door neighbour since he was a snot-nosed kid. Ever since he was young, he would always half-heartedly say that he would marry me or date me. I just passed it off saying it was cute but… Why is this guy so persistent?! On top of that, we have to work together from now on?? Fine, bring it on! What am I getting myself into?
