Doomsday: I Transmigrated Into a Supporting Character and Became a Chuunibyou Big Sis

“Simps should line up and get mowed down with AKs!” “Hopeless romantics deserve to be cut to pieces!” Dongfang Qing transmigrated to the time before the apocalypse, and even ended up as a female side character. How could a charming, adorable girl with silver hair and blue eyes be nothing more than an insignificant supporting character!? Being a side character was bad enough, but she was also the male lead's devoted simp and walking ATM. Her tragic fate was to be abandoned by him when the apocalyptic crisis broke out! Unacceptable! 【Ding! Congratulations, Host, you are now bound to the Apocalypse Era System!】 【Host can earn Impression Points by leaving different impressions on people, such as delicate, cute, aloof, chuuni, and more!】 【Impression Points earned for each label can be exchanged for various apocalypse-themed outfits, weapons, physiques, abilities, and other items】 Faced with this sudden System, the first impression Dongfang Qing thought of was chuuni. After all, men are boys until the day they die! She eagerly opened the label panel, then froze on the spot! 【Name: Lin Haoyu (Protagonist)】 【Age: 19】 【Impression of Host: ATM】 【...】 “The male lead has it easy. All he needs to worry about is people chasing after him. As a side character, I have a lot more to think about!”
