I read a novel long ago but for the life of me I just can't remember, its BL Danmei and basically the world (arc?) is that the ML and the MC of the world are into a melodramatic dog blood plot where the ML treats the MC as a substitute for the White Moonlight. Thats where the transmigrator comes in. He's the White Moonlight and he falls in love with the MC, he's a very talented artist I think and basically its very dog blood but comedic cause the transmigrator's POV is just hilarious lmao. I forgot what this novel is if anyone could help me I'd be eternally grateful!
