Suicide, no. Just no. That doesn't fit her character in the slightest. Losing everything, which she in no way had, wouldn't make her commit suicide. Wouldn't even cross her mind. She's been going through way worse things, and now she gets a fresh start. It feels so out of place with her in every way. The empress is a fighter and a hero inside and out, should have shown shattering those poison bottles.
Read Cursed Princess Club, it's finished and fantastic.
