One day, she woke up from bed and opened her eyes to realise she has transmigrated into the BL novel *Asterion's Starry Blue Night*. The protagonist of a crazy story who killed himself on the verge of death. I've become that protagonist's older sister... Rosalite! The issue is that if and when my brother, Asterion, dies, the system will automatically revert me back to the sixteen-year-old Rosalite! That is why I must protect my brother from a plethora of other assholes in order to avert infinite regression! Whether it's from a son of wealthy household, a prince of the country, or even the imperial prince from across the sea, no matter whoever it is.---One day, I woke up as Rosalite, the older sister of Asterion in the novel, *Asterion of the Twilight*. I may not be the main character, but it's not so bad. Rosalite's little brother, though, is fated to die in the story at 18 and that just seems really unfair after all the drama he's been through (did I mention his story is a BL?). Now that I'm Rosalite, I decide to save him. But no matter how hard I try, he just keeps dying and every time he dies, I turn back into 16-year-old Rosalite. Ten or so deaths later, I'm more determined than ever to save him. Rich, royal, or sexy foreigner: whoever touches my little brother will die!---**Original Webtoon:** [Daum](https://webtoon.kakao.com/content/%EB%82%B4-%EB%8F%99%EC%83%9D-%EA%B1%B4%EB%93%A4%EB%A9%B4-%EB%84%88%ED%9D%AC%EB%8A%94-%EB%8B%A4-%EC%A3%BD%EC%9D%80-%EB%AA%A9%EC%88%A8%EC%9D%B4%EB%8B%A4/2568), [KakaoPage](https://page.kakao.com/content/57361675)**Official Translations:*** [English](https://www.tappytoon.com/en/comics/touch-my-little-brother-and-youre-dead)* [Chinese (Simplified) / 汉语](https://manga.bilibili.com/m/detail/mc30748)* [Chinese (Traditional) / 漢語](https://tw.kakaowebtoon.com/content/%E6%95%A2%E5%8B%95%E6%88%91%E5%BC%9F%E5%BC%9F%E5%B0%B1%E6%AD%BB%E5%AE%9A%E4%BA%86/226)* [French / Français](https://www.tappytoon.com/fr/comics/touch-my-little-brother-and-youre-dead-fr)* [German / Deutsch](https://www.tappytoon.com/de/comics/touch-my-little-brother-and-youre-dead-de)* [Indonesian / Bahasa Indonesia](https://id.kakaowebtoon.com/content/If-You-Touch-My-Little-Brother-Youre-All-Dead/11)* [Japanese / 日本語](https://piccoma.com/web/product/80672)* [Thai / ภาษาไทย](https://th.kakaowebtoon.com/content/%E0%B9%83%E0%B8%84%E0%B8%A3%E0%B9%81%E0%B8%95%E0%B8%B0%E0%B8%99%E0%B9%89%E0%B8%AD%E0%B8%87%E0%B8%89%E0%B8%B1%E0%B8%99_%E0%B8%A1%E0%B8%B1%E0%B8%99%E0%B8%95%E0%B9%89%E0%B8%AD%E0%B8%87%E0%B8%95%E0%B8%B2%E0%B8%A2/303)"
