"This is a condo, not a nightclub!"
"Well, it isn't a monastery either, neighbor!"
'Mawin,' a peace-loving young architect armed with a perpetually fierce scowl, finds his sanity pushed to the brink on his very first day in his new condo. He immediately clashes with 'Arm,' an infuriatingly smug freelance photographer living in Room 1502, who makes it his daily mission to give Mawin a headache (and rattle his nerves).
From mortal enemies who bite each other's heads off at every encounter, to a 'karmic retribution' that refuses to leave his side... before he even realizes it, the annoying guy next door he swore to hate has already invaded the most private space of all—his heart!
