The upcoming offering is the P-Pop act's follow-up to their March comeback single 'WHAT?', which has garnered over 9.2 million views since its release.

A'TIN, the 'Alab' group's fandom, took to social media to share their thoughts and theories about the forthcoming single. Check out their reactions below.

Final theory ko na po:
Sa Buwan
-(sounds like Saan, and it also answers the question)
-based on teaser photo, world map can represent world domination, which is their dream and parang suntok siya sa buwan (kaya fusion yung images)++@SB19Official #SB19Saan #SB19

baka nga 5Ws yung songs nila no? one of the principles ng 5Ws eh something is considered complete if it answers questions that start with an interrogative word. yung who? what? when? where? why?

THEORY ulit.

The photo teaser depicts a phenomenon called annular solar eclipse. It symbolizes changes in vision. Looking at something new and finding a different route to one's goals.

I think this is why we are seeing a different side of @SB19Official now.#SB19Saan #SB19 pic.twitter.com/SNCgKKTlWX

Saan as the tagalog term of Where I can't help but to be amazed and chuckled about it!

They're so witty, it'll definitely catch the attention of many people

First is WHAT? now It's SAAN (WHERE) that hype us 😂@SB19Official #SB19#SB19Saan #SB19IkalawangYugto pic.twitter.com/yBG5iTfqZV

[THEORY]

Saan sounds like "Sun" and isn't it ironic on how it sounds like sun pero moon ung nasa picture? Anyway, what if "Saan" will be a song about staying strong and not loosing hope despite the challenges that we will encounter. Why? Read below. @SB19Official #SB19Saan https://t.co/EQiIRrjXQe
