They sung/rapped in Thai, Korean, Japanese, and English, hence the band name being "chaotic" with all the different languages. Yet, they made it work in my opinion.
They are no longer a group though, having disbanded in 2012 since Jongbae had mandatory army duty being Korean, and Poppy wanted to finish his degree at his university. But, I've seen updates here and there on social media and they still keep in contact.
Jongbae is a solo singer now, Tomo seems to be doing more acting, and not sure what Poppy, Kenta, and Koen have been up to.
Here are some of my favorite songs by them:
Making a sim of him was actually difficult. I'm not entirely sure why. I did have a bit of trouble finding the right eyebrows and getting his eyes right. Different photos, and his eyes appeared differently. Was frustrating. Either way, hope it's okay >.<"
I'm not certain how fluent he is, but he, Poppy, and Tomo do speak some English, from an interview I saw below :
He is playful, mysterious, and maybe mischevious as well at times.
He sings and raps in Thai, Japanese, and English, but is mostly the one who does the English verses.
