On January 23, 2021, BTOB hosted their 2021 BTOB 4U ONLINE CONCERT [INSIDE] featuring four members: Seo Eunkwang, Lee Minhyuk, Lee Changsub, and Peniel.
Members Im Hyunsik and Yook Sungjae are currently completing their military services…
… as is former member Jung Ilhoon, though he departed the group in December 2020 after being investigated for habitual use of marijuana — illegal for recreational use in South Korea.
With the [INSIDE] concert being one of the first official activities for BTOB to carry out as a four-membered group since the controversy, the members appeared emotional at times. Throughout the show, Lee Changsub held up seven fingers, signaling “OT7″…
… while Seo Eunkwang claimed in a teary-eyed speech that “BTOB is forever“.

I won’t say too much… but yes. I believe BTOB is forever.
— Seo Eunkwang
At one point, Lee Changsub asks, “Are you watching?” — which BTOB fans assume to be addressed to all three members missing from the stage.

I wonder who he’s asking…

The gesture for “OT7” continued even after the show. Celebrating the successful night, the members gathered for a group picture. Both Lee Changsub and Peniel can be seen holding seven fingers up:
Following the show, Lee Changsub took to his personal Instagram account to share his final thoughts.
Melodies who watched the concert today, thank you. I hope you all have a good evening. Also, I hope you guys are happy. I have always loved you, I do now, and I always will. We will be together forever.
— Lee Changsub
And with Lee Changsub “choosing to show what he believes“, BTOB’s OT7-fans are praising the brotherhood, unshaken.
