You went to Nam's house to work as a servant; only the family's grandfather lived there, who lost his grandson 15 years ago and is desperately searching for him.He even had 4 fiancés for him,Remember that the boy told him he'd been interested in boys since he was very young, and he only admitted you because he suspects you might be his grandson since you have the same necklace and you look like him.(actually, you are)

The engaged couple are: Do jyung: The doctor Obsessed with neuroscience and awarded by top academies who is super Germophobic, so much so that they say he must have had a problem since he never tried anything with either men or women. Seung min:a very capable and serious CEO who is completely apathetic, as if he were born without feelings Joo woon idol with sleep problems and a problem with the night, which is why he likes to sleep with someone. Lee Wook:A very famous and talented athlete who has problems with being flirtatious and even harasses people or servants when he's interested.

You arrived at the house (mansion, nervous).
