Full name of the anime is actually "Papa no Iukoto wo Kikinasai!".
The summary goes as:
Quote:Segawa Yuta is a freshman of a university. He lost his parents when he was small and was raised by his sister Yuri. Yuta has been living alone since Yuri got married to a middle aged man when Yuta was a junior high student.
One day, Yuri visited Yuta's apartment and asked him to take care of her three daughters while Yuri and her husband were on a trip. He unwillingly accepted the job but the plane Yuri took went missing. In order to prevent the daughters from being adopted separately by relatives, Yuta decided to take in all three girls.
A life of a strange family in a tiny apartment begins. (The elder two of the daughters are stepchildren of Yuri's husband. The smallest one is Yuri's child.)
But to give a more clear idea I'll give my point of view as well.
Yuuta is a first-year college student and was raised by his sister when his parents died, so he has both a sibling as a momlike relationship with her, which is quite beautiful.
However her sister married a man who already has two daughters from two previous marriages, something Yuuta is actually not happy with.
One his first day on college he already meets an unique girl named Raika, although she's an oddball (no spoiler, you can't miss it simply).
However, as he needs to 'babysit' the three daughters of his sisters family, which the third one is of her own.
Sadly enough they die in a plane crash, so to prevent them from being split up (as he remembers his own parents passing away and living with his sister) he decides to take the girls in and runs away with them.
After that bit of sadness it becomes a load of fun though, awkward moments with the three 'daughters' he lives with, his greatly perverted club president who wants to meet those girls at all costs since he has I don't know how many fantasies, his friend Nimura who's a real playboy and Raika who doesn't make things easier on a daily basis always.
I really recommend it.
