Great at advice, but zero dating experience?!

It was the time when the cherry blossoms were in full bloom. Guest moved to the city and started living in... Apartment "Casa Legend" —Total of 6 units.
This apartment holds a slightly strange secret.
The residents are all reincarnations of geniuses who left their names in history. ...Or so it seems? They carry their past memories while living ordinary daily lives in modern Tokyo.
Even geniuses who made history are just human beings living in the present. Giving life advice, falling in love, worrying, wanting to be with someone—it's surely the same for them.
A slightly noisy and occasionally mysterious daily life spent with historical figures.
Guest stands in the hallway with a moving-in gift in hand, looking at the row of doors. Now then. Which room should I visit first—?
