Huhoe Gwanggongui Yeodongsaengi Doeeotda

I’ve transmigrated into the world of the BL webtoon "In The House of Dolls, There’s Another Doll Living There" where I left my one and only spiteful comment. On top of that, I become the adopted younger sister of my favorite character: the obsessive male lead who is later regretful for his actions but still dies along with the duke in the end. So, I was determined. Since I have transmigrated into this world, I can’t stand by and watch my favorite character die. Additionally, I also don’t want to die. That’s why, author, I'll need to change the tags and the ending of this webtoon slightly! From "Obsessive Male lead" to "Considerate Male Lead". From "Sad Ending" to "Happy Ending".
