Detailed Summary
In Tadakuni's room, Tadakuni and Yoshitake are seated on the floor, with Hidenori on a chair. Yoshitake asks Hidenori what he did for question 4 on that day’s exam, but Hidenori deflects, saying that it doesn’t matter anymore. Tadakuni then snaps at them for lounging around at his place all the time and demands that they leave. Asking him to calm down, Hidenori agrees to go home and is about to leave, when he stops in his tracks.

All of a sudden, he asks Yoshitake what he thinks of skirts. Yoshitake seems reluctant to discuss it because it's dangerous territory, and Tadakuni once again yells at Hidenori to leave. However, to his dismay, the two are already engrossed in a conversation. They display horror at the minimal coverage offered by skirts and Tadakuni says they were designed to be comfortable during the Middle Ages. Ignoring him, they express how embarrassing it would be to walk with one’s underwear exposed, and their agitation steadily increases.

Panting, they recover from their exaggerated reactions, and Hidenori asks Tadakuni if they could borrow his younger sister’s skirts. The reply is an anguished negative, but Yoshitake then enters the room with said skirts in hand. He also produces the sister’s panties, adding that he had deposited his own underwear in its place, much to Tadakuni’s dismay. Hidenori and Yoshitake first wear the skirts on their shoulders instead of their legs before realizing their error, all the while ignoring Tadakuni who continues telling them to put them back. The duo then break out into an argument about whether it's okay to show one's leg hair in a skirt.

Tadakuni separates them and tells them it’s fine either way so they should just get it over with. The others label him a pervert for wanting to wear a skirt that badly, much to his consternation. He protests that he's just sick of their silly arguments. Eventually, the three find themselves each holding a skirt and Yoshitake and Hidenori take to different areas, saying they’ll change. Dismayed, Tadakuni asks if they were serious, before reluctantly heading off to change as well.

After a while, they all emerge blushing, with Tadakuni’s embarrassment being the most vivid. Seeing his friends staring blankly at him, he finds that he is the only one to have actually worn the skirt, much to his shock and distress. He attempts to club the others with a chair in his anger, before collapsing in defeat and begging them again to go home. They try to perk him up by saying he looks really good in a skirt, and that he could even make some money this way.

Buoyed by this false praise, he gradually comes around, and even strikes a pose for them much to their amusement. The boys then decide to take the game up a notch. However, just then, Tadakuni's sister happens to enter the house. She walks in on them attempting to dress a half-naked Tadakuni in her underwear, at which the boys scream in horror. She asks them what’s going on, and they begin to apologize profusely.
