Not sure if this is a place to talk about this (the thread title is Korean BL Stars, so I guess it's fine), but Kim Ji Woong, the main actor who played in BL dramas "Kissable Lips" and "Roommates of Poongduck 304", is currently participating in an idol survival competition reality show called "Boys Planet" (to be aired on February 2023).
Here's his profile in said show (although this pic doesn't do him justice):

And here's a link to his video cam performing the show's main theme-song:
For those not familiar with the show, "Boys Planet" is the 2nd season of Kpop idol competition reality show from the "Planet" franchise, created by Mnet (a famous Korean music channel/company), where 99 idol trainees from different agencies or individuals, from South Korea & many other global countries, compete in securing the final top spots to debut in a temporary idol group that would usually last for 3 - 5 years. Viewers would have the chance to vote for their favorite contestants, so if you want to support Kim Ji Woong, you may have the opportunity later when it aired.
If you are familiar with "Produce 101" franchise, well, it's because this is basically the same but under a different name (the original "Produce 101" franchise director and team got caught for rigging the result and are now in jail). Surprisingly many "Produce 101" alumnis have starred in BL series. Kim Ji Woong's BL partner in both "Kissable Lips" and "Roommates of Poongduck 324" was Yoon Seo Bin, also a former contestant in "Produce x 101" (the 4th season of "Produce 101" franchise), although he was cut early on & forced to quit due to a past bullying scandal.
