Ep. 2: Yui wakes confused in a nightgown surrounded by brothers before being forced to obey Ayato instead of attending night school.

2

Yui regains consciousness in a comfortable bed, dressed in a nightgown, with no recollection of how she arrived in that attire. While she attempts to understand her situation, she is immediately surrounded by her five younger brothers, who begin arguing over who gets to claim her attention. The eldest brother, Ayato, arrives and abruptly instructs her to prepare for night school. He warns her to behave properly or face punishment, though Yui is unclear about the specific expectations. Instead of going to class, she finds herself compelled to submit to Ayato’s every whim, leaving her confused about the nature of her required conduct and the circumstances of her current situation.
