If you're looking for a light-hearted series, this one is for you. Definitely not an ordinary reverse harem, no need to step back from seeing the tags.

Despite being light-hearted, the story makes your heart feel like getting a warm hug. In the family story, each of the character's personal stories is brought up very well. When they're solving each other problems together until they solve their common problem, it makes you realize again how dear is family can be no matter related by blood or not.
No need to question Horikita Maki's acting. Her voice tone and expressions are really good. Her acting screams what her character feels really well. Being her fans after watching this series (It's a shame that she retired but I understand and respect her decision).
