Three brothers lead the life of bachelors and their rent is overdue. The landlord who also happens to be a matchmaker tries to marry off the oldest brother to a rich girl.

When Amalia Balash starts working alongside Georg Nowack at Mr. Maraczek's Parfumerie, the two argue endlessly, while unknowingly writing loving words to each other as a part of an anonymous "dear friend" romantic pen pal service. When Georg finds out who his "dear friend" has been, he looks at their relationship and realizes all that animosity he thought he felt may have been nothing less than love in disguise.
