'Bad Idea': Astro's Moonbin and Yoon San-ha make sub-unit debut, 'speechless' K-pop fans are losing their minds

The duo's first mini-album 'In-Out' was released along with their debut single following a stream of teaser images and videos that included a highlight reel for the release

Members Moonbin and Yoon San-ha of South Korean boy band Astro have made their official debut as a sub-unit with the release of their song 'Bad Idea' and their first mini-album 'In-Out'. The release comes only a few months after Astro dropped their digital single 'No, I Don't' which they performed for the first time during their '2020 ASTRO Live on WWW' virtual concert the day of its release.

Astro debuted in 2016 under Fantagio Music with six members, Cha Eun-woo, MJ, JinJin, Moonbin, Rocky, and Yoon San-ha. Their first single, 'Hide & Seek' off their debut EP 'Spring Up' earned them global praise, and the group landed themselves on Billboard's list of the best new K-pop groups of 2016. 'Spring Up' went on to hit number six on the Billboard World Albums Chart within a week of its release as well as number four on the Gaon Music Chart. Their second EP 'Summer Vibes' followed a few months later, and once again peaked at number six on the Billboard World Albums Chart. After a stint at KCON 2016 in Los Angeles, the group dropped their third EP 'Autumn Story'. In February 2017, Astro dropped 'Winter Dream', the fourth and final release in their seasonal album concept. Despite it being the completion of their debut project's journey, the album was not officially promoted, and their next release 'Dream Part.01' is often listed as their fourth EP. Several more EPs, concerts, and charting releases later, and following an eight-month hiatus, Astro returned with their first full-length album 'All Light' in 2019, which was followed by a tour and the group's first music show award as well as the group's Japanese debut.

2020 has been good to Astro thus far, beginning with the release of their special single album 'One&Only' to commemorate their fourth anniversary since their debut. They also dropped their seventh EP 'Gateway' in May, and earned their second music show award for their song 'Knock'. And in June, they held their '2020 ASTRO Live on WWW' virtual concert. And now, four years since their debut, the group is presenting their first sub-unit with members Moonbin and Yoon San-ha. 'Bad Idea' serves as the lead single for 'In-Out' and features the duo locked in a battle, one that their fans couldn't have quite predicted going into this.

"MOST OF US TALKING ABT BIN SAVING SANHA FROM BAD DREAMS BUT WE GOT..." tweeted one fan, "So Moonbin controls Sanha’s dreams then what," asked another, and one fan said, "To all the Arohas who kept saying they were going to whoop whoever dared to hit Moonbin none of y'all guessed they'd hit EACH OTHER!!!!"

"While watching the MV by brain was malfunctioning like I didn't know where to pay my attention to. The song? The MV storyline? The wound on Binsan's face? Wkdjskeksmskk no don't talk to meee—" "WTH THEY LOOKED SO GOOD," "So much to say and yet speechlessssss," "ITS SO GOOD IM CRYING I REALLY AM PROUD OF YOUUU."
