about xavier's flower!! visually the ones in official material definitely are forget-me-nots! i feel like the naming has to be some sort of misunderstanding or mistranslation because briefly searching online, it seems like 星辰花 is used to refer primarily to statice (wavyleaf sea lavender) but also forget-me-not? and i presume they used 星辰花 over 勿忘草 for the star reference which i love and makes me so :'))))) but also probably led to confusion on the translation side, but i could be wrong too!!
