I Can Still Be a Mary Sue

Player D visited her loyal Ani empire. This is an otome game that mixes various elements. The male characters that can be conquered include but are not limited to sons, knights, elves, demons, angels... This game was designed by her best friend herself. What else is there to say? Player D rolled up his sleeves and got on, vowing to be the first to pass the level. However, Player D's main mission is a bit strange: [You are the only heroine in this world, but please don't be tempted by her] Don't stop. Don't look back. Don't... Don't... No... Don't go Don't go, don't go, don't go, don't go Reminder before reading: 1. Literally a Mary Sue otome novel, everything revolves around the heroine 2. A free-spirited heroine with a very stable core of contentment x a paranoid male protagonist who will die immediately if he can't attract the heroine Concept: Non-humans also need to fall in love (?)
