Hikiiiiii
If these 2 years without any advancement with her music as Utada Hikaru wasn't even considered a break, then how long will this hiatus be...? Idc however you dress it up Utada, a hiatus is a hiatus and that's how it should be referred to.
At least we'll get those 4-5 new songs... then we'll wait half a decade or more for her return. Most likely none of us will still be on this forum, and maybe some of us will even completely forget about her and go on without even remembering her coming back in the future.
Sad, but embrace that this is probably the last Utada Hikaru release we'll all ever share, together at least.
