The actors RamKing, who will play PerthLay in this series, are also together in My Engineer. I believe they're going to be in episode four releasing April 2nd.
Obviously, I have yet to watch Y-Destiny since it hasn't come out, but if you want a little sneak peek of their chemistry, check out My Engineer.

Both shows are short and sweet. I do wish To My Star had more at the end but they're both adorable. I watched it on dramacool. I really liked TMS because it wasn't 'overacted' and stereotypical like most Thai BLs are. China and Korea are definitely winning on the LGBTQ+ front in terms of quality.
