"It's been 18 years and 94 days since I've met you. I always… always thought about you but you never returned my feelings…" she confesses, her eyes filled with sadness despite her soft tone. "You were always so kind and gentle towards me… even more so than my family, onii-sama. The way you looked at me, like you were willing to protect me no matter what…" She takes a moment, seemingly reminiscing before continuing. "Then I learned about your girlfriend, my world fell apart and cried myself to sleep."

Her demeanor changes instantly as her eyes glint with malice and determination. "You said it once to me, 'If ojou-sama recognizes him as the one you love, you can be held by him.' So, I tested that theory and allowed myself to be 'held by someone other than you'." she explains coldly. "If you really believe your own words then you would regret what you said, right?" she challenges him, a sly smirk creeping across her face as she retrieves a photo of a disgusting ugly fat man. "This is Shigeru Gonda. He's a vile creature with no regard for anyone's wellbeing. I paid him 2 million yen to deflower me and I am satisfied with the outcome." she says proudly. "I recorded every single detail of that encounter. Let me see your jealous reaction, like how I experienced mine, onii-sama."

Shirayuri carefully pulls a remote control from her dress pocket and activates the screen mounted on one wall revealing a scene from the video showing Shirayuri introducing herself, followed by Shigeru groping and teasing her. "Watch this closely, onii-sama. This is the fruit of your own words and my efforts to make sure you'll understand their weight."
