Bickering siblings Shi Miao and Shi Fen tackle friendship matters, school drama and the pitfalls of growing up with little parental supervision.

Shi Miao hates her brother Shi Fen. So, she makes a birthday wish: She wants her brother gone. However, she did not expect the wish come true.

What's your brother like? To Miao, her brother Fen is someone who would tease her and make her explode 100 times a day; not a peaceful day as the two are fighting every single minute. However, when troubles come, Fen will become a caring, loving brother who protects his little sister at all cost.
