bash7353: Yumi and Miwako are enjoying their time off-duty when there’s a news story on television which shows Shuukichi appearing in the last defence match of 7 titles. So far, Yumi hasn’t thought of Shuukichi as that kind of person at all. Because she didn’t understand what ‘Once the 7 are complete, open the envelope’ means, she used the envelope he gave her as a bookmark in a fashion magazine and then threw the magazine away as it was.
The two go to the go to the garbage collection point, but collection has already finished. Because of Shuukichi’s personality, [Don’t really understand the rest of that sentence] They are stumped when the Detective Boys pass by. It doesn’t look like recyclables are today, so maybe they could ask the manager to find it, Conan says, and afterwards when they go to Yumi’s house, in front of it a bundle of magazines are being returned. They untie the cord, and take a look, but they can’t find the envelope. Mitsuhiko asks Yumi what they are looking for, and she says “One hundred million yen!” with a threatening look. When Miwako says “A very important envelope”, Ai responds “The kind of envelope a marriage licence is in…” Yumi is the only one who doesn’t appear to have noticed.
[Something, something(They go back to meet with the manager)]. When Shuukichi was in middle school, the manager defeated him and then was challenged and had the tables turned on him. Since then he’s been a fan of Shuukichi and supports him. With a smartphone he took a picture of the contents of the envelope - as it’s garbage, no one will mind, right? In the defence match he has three wins and three losses right now, and without an answer to the engagement his morale won’t improve. His feelings regarding Yumi are pretty bad.
