The frustrated New Yorker Matthias inherited a Paris apartment from his father. He came to Paris to sell the apartment, but accidentally discovered that there were two "nails" in the house-an old woman from England, Matil. According to complex real estate regulations, Matilde, the long-time tenant, will have the right to ask for monthly rent from Matthias if the landlord sells the house, according to complex real estate regulations, until her death.
Madias, who had nowhere to go, reached a temporary residence agreement with the mother and daughter, but in private he still contacted the real estate developer to sell the house, which made Chloe wary of Madias. However, when two people who meet by the water find that they have a lot in common, how will their relationship develop unexpectedly? What secret is hidden by the old-fashioned Matilde?
