1. Lee Su Ho’s passcode

In episode 6, Lee Su Ho is seen entering a passcode to unlock the secret room in his apartment. The passcode appears to be 0223 – could this be a nod to ASTRO’s debut date, February 23?

2. The posters at MOVE Entertainment

Posters inspired by ASTRO music videos can be spotted on the walls of MOVE Entertainment, the company Lee Su Ho’s father owns. Here’s one from episode 8 featuring a scene from their “Blue Flame” MV!

3. This iconic line

The ultimate fan-favorite was definitely in episode 7 when Im Ju Gyeong, played by actress Moon Ga Young, asked Lee Su Ho to go with her to the comic book store by using Eunwoo’s beloved line, “같이 갈래?” (“gachi galae?“) from the ASTRO song “Polaris.”

Although he replied with a curt rejection, fans were rejoiced to catch this subtle nod to their favorite group.

4. Moonbin and Sanha’s alter-egos

The most recent – and obvious – Easter egg has to be the appearance of members Moonbin and Sanha as the fictional group ATEEN in the latest episode!

Here’s hoping the rest of ASTRO will make an appearance soon – and not just in a static picture!
