In love si Carlo kay Colleen na ang akala ng lahat ay kapatid niya. Pero mukhang mas may mabigat pa siyang problema. Ang karibal niyang si Elijah na obsessed dito.

One of the lady boarders is having a some-kind-of-an-"it's complicated™"-ish-affair with the owners' only son. To make matters even more "it's complicated™"-ish, their affair is kept as a SECRET. Will their love survive amidst the preying eyes of the landlady/the guy's mother? What of the other issues, as well?
