The Struggles of Being Reincarnated as a Sibling

Makoto Tuki is a popular high schooler living in Seoul, South Korea. He has plenty of skills such as writing and piano, plus a nice face. But he has a secret. He is obsessed with otome games. A secret passion of his that nobody knows about. His favorite is called Painted With You, a reverse harem with 8 handsome capture targets. He has played through the entire game, and found a secret route in which he became friends with the evil villainess. A route that was previously not discovered. When he is given notice of an update coming out to play as the villainess, Lafinia, he is overjoyed. And thats exactly when Truck sama struck.
