Inso's Law Webtoon
probably one of the best manhwas, I have ever read. The plot is so interesting too. I liked how they also involved the hair colors too. The female lead is from another universe (or parallel universe I think), and also is friends with the 'Female Lead' (that's what she thinks, but it isn't). Things are confusing at first from changing of timelines. The comedy is amazing. I love that they have each others backs and always stick together.

How could the OG Female lead and Male lead do this to him Like after his many sacrifices for his friend and the woman he loves, he was the one getting hurt in the end. All second male leads deserve the whole universe!!
