Having overnighted with Jan Di's family, Joon Pyo gets immersed in their commoner lifestyle and habits. Enjoyable, till an ungentlemanly charmer goes too far.
It's Valentine's Day, and upon seeing Joon Pyo making a public fool of himself, Kang Hee Soo takes actions to remove the Jan Di "weed" from his social garden.
Homeless (thanks to Hee Soo), Jan Di winds up as a maid in the Kang mansion (thanks to Joon Hee), becoming Joon Pyo's personal servant (thanks to the observant head maid).
