I’m thinking he’s going to propose a marriage between Sei and the second prince
That was exactly my thought. They’ve done too much to set this up with the episodes this season. The “you’re gonna lose her, someone else is going to take her” speeches in previous episodes, all the dudes at the ball hanging around, and of course the prince that she didn’t know about before all of a sudden showing up wanting very much to meet her. It all adds up to exactly what you suggested. I’m curious to see how it plays out.
Last year I think. The lead singer has started a new project called Q.I.S (Queens in Sweaters) with 3 songs out so far, plus she wrote stuff for halca and performed some with Kana Boon. Miku (the drummer) is doing some DJ sets and playing drums with some other bands. The bassist seems to be taking a break for now and hasn’t been up to much.
