i just wanna throw this out there into the void that isn't twitter for once, but there's just a whole lot of things still unexplored in regards to Chu2. But what i think is an important factor to her character is the fact that on Radio RIOT they confirmed that the song "Takin' My Heart" is a song about her feelings/beliefs, canonically written in the Bandori universe by her. all the RAS songs technically are, but theres that specific confirmation on this song that it was w her perspective in mind.
if you know me vaguely you probably also know that i never shut up about this fact and like to bring it up a lot sdgjhhjfdgfg

those kinda lyrics just feel like a punch in the gut. they're really raw and sad, they truly give more perspective into Chu2's character. Raychell even admitted to having cried to this song when she practiced alone
i'm really interested in seeing what they've planned in regards to Chu2. there's clearly a lot more they've got to show off when it comes to her, and hopefully that'll actually happen 'cause Chu2's just an interesting character to me
