As I watched Our Times (我的少女時代) I noticed Hsu Taiyi was wearing a Casio Calculator CA53W watch… I have one too! You will see in the show that he almost never takes it off, and the things he’s been through show how hardy this watch actually is.
Also, watch this video if you liked the theme song! There’s something about this… It’s like David Cook doing Always Be My Baby. Hahahaha.
