YG rookie group TREASURE MASHIHO taught Park Jung-woo how to tidy up his room.

YG Entertainment unveiled "Three Minutes TREASURE-Organization Episode" on its official blog and TREASURE official YouTube channel at noon on April 20.

In the video, Park Jung-woo introduced Mashiho as "the best cleaner, the cleanest person." Mashiho said, "He does clean up. But he can't maintain well after cleaning," he said, drawing laughter.

Since then, the two have begun cleaning their rooms for spring in earnest. Looking at the room of Park Jung-woo and Yoon Jae-hyuk, where clothes are scattered, MASHIHO said, "It's cleaner than before."

Before cleaning, he said, "We have to start cleaning from the top because of the dust. At the end, you just have to clean up the dust underneath," he said, revealing a tip.

Masaho and Park Jung-woo folded their clothes and started cleaning the room. MASHIHO explained to Park Jung-woo, who is agonizing over where to clean up. Park Jung-woo said, "When (Mashiho) comes next time, I will be Park Jung-woo who is good at cleaning."

Park Jung-woo asked Masaho, "How often do you clean?" while cleaning. Mashiho said, "I clean up every other day. I think I learned it because my parents are neat," he said, explaining how he got organized well.

Park Jung-woo then helped Mashiho by vacuuming the room. MASHIHO showed his passion as a "master of organization" until the end. Park Jung-woo and Yoon Jae-hyuk's room, where the cleaning was completed, looked more organized than before, including their clothes, desks and beds.

After finishing cleaning up, Mashiho said he was "cleaner than I thought." Park Jung-woo said, "I will try to maintain a clean room. I'm grateful to Mashiho," he smiled.
