Beast World's Pampered Pet: After Transmigrating into a Book, I Became a Heartthrob

What made her break down was that the illnesses from her previous life had transmigrated along with her! To make matters worse, she arrived in the middle of winter! The moment she opened her eyes, she was facing a hell-difficulty start! In order to survive in this dangerous world where wild beasts ran rampant, Su Yu could only work hard to find people. But as she kept looking... Huh? Why are all the big shots from the various tribes in her nest? —— The stubborn and tsundere wolf youth placed all his prey before her: "No matter how delicate or hard to raise Yu Yu is, I can still raise her." The gloomy and paranoid dual-personality snake beast: "Yu Yu, you've provoked me; don't even think about leaving for the rest of your life." The domineering yet gentle winged-tiger youth kissed her softly: "As long as you are safe, I would give you my very life." The exquisite and melancholic merman youth held pearls in both hands: "Yu Yu, from this day forward, my tears shall only fall for you."
