I don't know about that one. What I would have watched would likely have been Chinese, Korean, or, less likely, Japanese. The only Taiwanese drama I watched that long ago last year was Before We Get Married, but I can't figure out if that was it, either. I know the ex was crazy obsessed with him.
It is also entirely possible I didn't watch the whole drama I described but only that part on YouTube or something. I am hoping I didn't just imagine it and am not thinking about something I read. Who knows, maybe it was a webcomic and I am confused? I just felt so sure I had watched it before.
