End scene of Chapter 39. Evidently as a continuation of the talent show, Hidenori and Yoshitake make milk come out of their noses.

Detailed Summary
Tadakuni’s younger sister and Yoshitake’s older sister are at a café along with a bespectacled boy, who is revealed to be Hidenori’s older brother. He nervously asks them what they wanted to talk about. Yoshitake’s sister responds that it was something regarding all their brothers. Addressing him as Yūsuke, she adds that the boys needed to act their age. She reminds him that he used to be their ringleader when they were kids and that they might listen to him.

Yūsuke concedes this and Yoshitake’s sister, briefly changing track, asks him if the girl who accompanied him to the café was his girlfriend. He replies that she is. Yoshitake’s sister immediately stands up and tells Yūsuke she's loved him all along, startling him. Tadakuni’s sister notices that his so-called 'girlfriend' doesn’t react at all. Yūsuke then admits he was lying and that the girl was just a senior at a club of his. He is accused of showing off, but he deflects and tells them to get back on track.

Continuing about the boys, Yoshitake’s sister points to Tadakuni's sister and tells Yūsuke that they stole Mei’s panties. She adds that they also did something horrible on Christmas Eve. He asks if that was the time she ended up alone on the street and tells her he’s never seen her cry before that. He stops himself upon seeing her frosty reaction, but she slowly gets up and approaches him, sure of the fact that someone had sent him a snapshot of the incident.

Tadakuni’s sister puts Yūsuke into a headlock. As he struggles to move, Yoshitake’s sister reaches for his pocket to get his cell phone. She ends up pulling out a pair of panties instead and expresses confusion. Tadakuni’s sister identifies it as her own underwear and twists her arm further in anger, crushing Yūsuke’s spectacles.
