New Project from Desire4: 情执 (Obsession/Emotional Attachments)
The caption implies this is likely a second acting collaboration.
"Once emotional attachments are broken, the world opens up. Looking forward to seeing "Emotional Attachments"! P.S. Everyone has improved so much in both singing and dancing! Hoping for surprises in acting too!"

It also comes with a new song. It's not clear yet if this is a live action, donghua, or something else. There is no synopsis so I don't know if it is an adaptation or an original work, and the sisters aren't replying to fan comments under the post. Will update when more info is available ☺️
It's also the one-year anniversary so an announcement around this time makes sense.
Update: The sisters had a voice live about an hour ago, will update once we get translation.
00:49:16,800 --> 00:49:18,000 "Is Obsession a second collaboration?"
2006 00:49:18,000 --> 00:49:19,400 Yes, that’s right.
2007 00:49:19,400 --> 00:49:21,000 Maybe on some day
2008 00:49:21,000 --> 00:49:22,400 When we have more time
2009 00:49:22,400 --> 00:49:24,000 We can all chat about it together
2010 00:49:24,000 --> 00:49:24,800 Thank you, everyone
