Not sure if I should put it on spoiler or not, but oh well... I wanna ask people who read Side Character Transmigrations: the last boss is no joke, can you tell me which arc have the "male lead"..?? Thanks for the answer...
how about other arc..?? I know he sometimes appear sometimes it's not the "male lead" For example in vampire arc he appear again if I'm not mistaken
After that, he appeared in every arc I've read. Go to https://www.blobtranslations.com/side-character-transmigrations-the-final-boss-is-no-joke/ and in the glossary, it states the ML name in that world. And Shi Sheng has a way to recognize him.
