During the showcase, Pentagon mentioned their connections to various Cube Entertainment family members like HyunA, Wanna One's Lai Kuan Lin, Yu Seon Ho, and more. E'Dawn said, "HyunA noona told us that we looked really cool, that the styling and concept are very cool, and that she expected something big for this comeback, which boosted our energy." 

Jinho was asked about his good friend Gong Seung Yeon appearing in Pentagon's film teaser. He shared, "While we were thinking about who would fit with the concept we had in mind [for 'When I Was In Love'], talk of my friend came up, so I called and asked for a favor, and she thankfully obliged." 

Yeo One didn't leave out fellow Cube family members Lai Kuan Lin and Yu Seon Ho, saying that the two often told Pentagon how much they liked listening to Pentagon songs. "We've become people who cheer one another on, and even from here on out, we hope that Kuan Lin, Seon Ho, and all of Cube work hard and become a tight-knit family."
