Amagami SS: Nakata Sae Arc, Chapter 2: Training

Sae's training to become a waitress continues with the help of Junichi and Miya, by practicing her speech skills and practicing how to change uniforms in three minutes--where Miya catches her, in a swimsuit, and Junichi in a compromising position when Sae tripped. They even have had special training in a hot spring with some doctor fish in it to further her speech skills. Sae expresses to Junichi her desire to train even harder, though he has little idea why she wants to be trained more. Her trainings did make Sae become closer to Junichi and Miya; however, one night when Sae has to sleep over at the Tachibana residence, Junichi tells her his wish that he would like to have another younger sister like her, but, to his surprise, she says doesn't want that.
