Wit's manga / #dating sim(3)

After getting in an accident while testing out a new virtual reality dating sim, Gowoon finds that his life has become just like the game! He now has to complete the paths for three male love interests while also dealing with system errors. The uke is so cute and spunky. When he was a cat it was so good

Already 10 times better than I expected it to be. After accidentally finishing a story arc of his sister's dating sim, they fight, and the bro gets knocked out only to wake up in the world of the dating sim! Obviously he is minor villain character who doesn't want to play the part of the villain and accidentally makes all the male leads fall in love with him. Such a curse. But really, great world building. Like there's a lot of plot going on here
