The comedy lives in the space between "I want to kill my sibling" and "I'd actually die for them," and this show mines that exact feeling for 24 episodes without running out of material. Shi Miao and Shi Fen's dynamic stops being funny because of what they do to each other and becomes funny because you recognize yourself in every stupid argument. The second season stretches the formula thinner than the first, but the character growth sneaks up on you, suddenly Wan Sui matters, suddenly you care about these people beyond the gags.

Shi Miao's patience wears thin. Her brother Shi Fen keeps up his absurd behavior, and she has had more than enough of it. Shi Fen, for his part, just wants to get away from a sister who answers him with her fists. Their friends and classmates are along for the ride again this season. What emerges is a chronicle of two people locked in a dysfunctional bond, siblings who grumble about each other yet stay devoted all the same. The show is a slice-of-life comedy built on everyday sibling friction.
