I don't remember if it was a manhwa or manhua. I'm pretty sure it was really similar to monochrome syndrome and love rival is getting prettier. The bottom woke up as someone else that was famous for being really trashy and has a unrequited love. He decided to change and the seme thinks it all the get his attention. I didn't get that far into the story so I don't remember much but the uke had a piercing on his guiche. Please help me find it , I've been going crazy looking for it. 😩

I asked a friend who thinks this one is called Kill the Lights. Hope this helps in some way!

The plot sounds very familiar, like a combination of drama and body-swap. The piercing guiche detail is also quite unique, people in the industry will probably remember it right away. Hopefully someone will recognize it to help you (and us) get rid of this headache 😩
