TO BE FAIR I have rewatched the church bts video several times and it does look like they are not saying anything to each other. Their lips are hardly moving. DD even asks her « What are you doing actually? » at the beginning, probably joking because she is not doing anything, just approaching her face to his ear and moving her lips and that just makes it « awkward »! 😉 THAT BEING SAID there was a real exchange between them, not verbally but with their body language and smiles which is not nothing.
